Question

Find the greatest common factor of the pair of numbers.

348 and 426

Answer 1

6

Answer 2

Could you explain how you got that?

Answer 3

From Mathematica:
{FactorInteger[348], FactorInteger[426]}
{{{2, 2}, {3, 1}, {29, 1}}, {{2, 1}, {3, 1}, {71, 1}}}

Answer 4

they are both even so they are divisible by 2

the digits of each add to a multiply of 3 3 + 4 + 8 = 15 and $ + 2 + 6 = 12

so they are divisible by 3

since they are divisble by 2 and 3 then they are also divisible by 6

Answer 5

I listed out the factors of both numbers (got help from the internet doing that since these are big numbers) and the greatest common number there is your answer

Answer 6

a simple way is to use a factor tree



then you can see the GCF

Answer 7

so the GCF is
