Given numbers are 651, 688, 660, 105

The list of prime factors of all numbers are

Prime factors of 651 are 3 x 7 x 31

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 105 are 3 x 5 x 7

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 651, 688, 660, 105

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(651, 688) = 447888

GCD(651, 688) = ( 651 x 688 ) / 447888

= 651 / 688

= 651

Step2:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1

Step3:

LCM(1, 105) = 105

GCD(1, 105) = ( 1 x 105 ) / 105

= 1 / 105

= 1

So, Greatest Common Divisor of 651, 688, 660, 105 is 1
