Question

find the greatest commom factor of 2730 and 9350.

Answer 1

thats a long one - its best to you use euclids method here
- can't remember it!

Answer 2

a=bq+r.is it?

Answer 3

Prime Factorizations:
2730 = 2*3*5*7*13
9350 = 2 * 5 *5 * 11 * 17

GCD is therefore 10. :-) Is that one of your choices?

Answer 4

ya......thx

Answer 5

don't know
i think you subtract them first
9350 - 2730 = 6620
then
6620 - 2730 = 3890
3890 - 2730 = 1160
2730 - 1160 = 1570
1570 - 1160 = 410
1160 - 410 = 750
750-410 = 340
410 - 340 = 70

gcf of 70 and 340
70 = 2 * 5 * 7
340 = 2 * 2 *5 * 13

gcf = 5 * 2 = 10

Answer 6

lol - it would have been easier to factor!!!!

Answer 7

That's what I did ;-) Prime factorization. /me points

Answer 8

ya by lemma its easy
..anyways thx

Answer 9

yep - you really need to do the euclid thing on a spreadsheet

Answer 10

kk.

Answer 11

when you have really high numbers then euclid is very useful

Answer 12

ya it will:)
