10,20,30,40,50,60,70 (keep counting by tens)
There are no whole numbers that satisfy those conditions. If that was -3, you could use 3 and -1.
They have the prime factors 2 and 5 in common.
80= 2*2*2*2*5 35= 5*7 The only factor they have in common is 5, so the answer is 5.
50 = 2 * 5 * 5 30 = 2 * 3 * 5 So the common factors would be 2 and 5. The greatest common factor would be 2 * 5, or 10.
The common factors are: 1, 2, 5, 10
The common factor of 2, 5 and 10 is 1.
The common factors are: 1, 2, 5, 10
Least Common Multiple (LCM) for 2 5 is 10
The prime factors of 160 are 2, 2, 2, 2, 2, and 5. The prime factors of 195 are 3, 5, and 13. The prime factors they have in common are a single 5, so 5 is the greatest common factor.
The Greatest Common Factor of 5, 315, 2: 1
The greatest common factor of 2, 5, and 6 is 1
The common multiple for 2 and 5 is 1 cause both of the numbers are prime.
