Given numbers are 651, 637, 614, 515

The list of prime factors of all numbers are

Prime factors of 651 are 3 x 7 x 31

Prime factors of 637 are 7 x 7 x 13

Prime factors of 614 are 2 x 307

Prime factors of 515 are 5 x 103

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

Given numbers are 651, 637, 614, 515

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

Apply this formula for all numbers.

Step1:

LCM(651, 637) = 59241

GCD(651, 637) = ( 651 x 637 ) / 59241

= 651 / 637

= 651

Step2:

LCM(7, 614) = 4298

GCD(7, 614) = ( 7 x 614 ) / 4298

= 7 / 614

= 7

Step3:

LCM(1, 515) = 515

GCD(1, 515) = ( 1 x 515 ) / 515

= 1 / 515

= 1

So, Greatest Common Divisor of 651, 637, 614, 515 is 1
