GCF: 7 LCM: 210
Divide 98 and 210 by their GCF, 14 210/98 = 15/7 or 2 and 1/7
Oh, dude, let me break it down for you. So, if the greatest common factor (GCF) is 7 and the least common multiple (LCM) is 210, the number pairs would be multiples of 7 that multiply to 210. So, the number pairs would be 7 and 210. That's it. Easy peasy lemon squeezy.
The GCF of 210 and 735 is 105. This leaves you with 2 and 7. There are no further divisible numbers in common (aside from 1).
