Numerical Answers Expected!

Answer for Blank 1:

Answer 1

30

Answer 2

Simply list the multiples of each number (multiply by 2, 3, 4, etc.) then look for the smallest number that appears in each list.

Answer 3

OK

Answer 4

Choose the number that both 5 and 6 can divide?

Answer 5

what is the smallest number that both 5 and 6 can divide

Answer 6

I was thinking the same that you will add that only.. :P

Answer 7

all numbers are some product of primes
5=5
6=3*2

the smallest number therefore that 6 and 5 can divide is a number with the divisions 6 and 5 in it
3*2*5 <--- therefore these primes must exist

Answer 8

1

Answer 9

IS IT 1

Answer 10

Guys, lowest common multiple means, the multilpes of 5 and 6 whhich has the same multiple that is the lowest

Answer 11

You are finding GCF not LCM..:)

Answer 12

@dyamondsr4ever 1 is HCF or GCF, it is not LCM..

Answer 13

there is a way to look at it
list the multilpes of 5
5,10,15,20,25,30,35..
multilpes of 6
6,12,18,24,30,36 what numbers are common the smallest common multiple??? is 30

Answer 14

I CANT FIGURE ITOUT PLEASE HELP ME

Answer 15

Find a number so that when you divide the number by 5 you get 6. and if you divide the number by 6 you get 5.

Answer 16

30

Answer 17

yes.

Answer 18

Two things are there..

A largest number that can divide both given numbers --------> HCF

A smallest number that can be divided by both given numbers ---> LCM

Answer 19

THX GUYS I UNDERSTAND!!!! THX @dan815 FOR GIVING AN EXAMPLE

Answer 20

welcome

Answer 21

there is a more efficient way of doing LCM which is to look at primes factors

Answer 22

5=5
6=3*2
there fore 3*2*5 is the lowest possible LCM
for example if u look at
4 and 8 LCM
here 4=2*2
and 8 =2*2*2
all it has is an extra 2
we write out the common prime factors
2*2 from 4 and another 2 from 8
so 2*2*2 is the smallest possible multiple in other words like we already know 8 is the smallest LCM of 4 and 8 since 4*2 = 8

Answer 23

one simple thing to note is
if you have a number X and Y
and the prime factors of X do not include Y then the smallest possible LCM must be
X * Y

Answer 24

for example 50 =5*10=5*5*2, therefore suppose i say
hey whats the LCM of 3 and 150
since 3 is not a prime factor of 50
then 50*3 =150 must be the LCM
