Given numbers are 651, 515, 925, 720

The list of prime factors of all numbers are

Prime factors of 651 are 3 x 7 x 31

Prime factors of 515 are 5 x 103

Prime factors of 925 are 5 x 5 x 37

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

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

Given numbers are 651, 515, 925, 720

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

Apply this formula for all numbers.

Step1:

LCM(651, 515) = 335265

GCD(651, 515) = ( 651 x 515 ) / 335265

= 651 / 515

= 651

Step2:

LCM(1, 925) = 925

GCD(1, 925) = ( 1 x 925 ) / 925

= 1 / 925

= 1

Step3:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

So, Greatest Common Divisor of 651, 515, 925, 720 is 1
