Given numbers are 475, 515, 642, 651

The list of prime factors of all numbers are

Prime factors of 475 are 5 x 5 x 19

Prime factors of 515 are 5 x 103

Prime factors of 642 are 2 x 3 x 107

Prime factors of 651 are 3 x 7 x 31

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

Given numbers are 475, 515, 642, 651

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

Apply this formula for all numbers.

Step1:

LCM(475, 515) = 48925

GCD(475, 515) = ( 475 x 515 ) / 48925

= 475 / 515

= 475

Step2:

LCM(5, 642) = 3210

GCD(5, 642) = ( 5 x 642 ) / 3210

= 5 / 642

= 5

Step3:

LCM(1, 651) = 651

GCD(1, 651) = ( 1 x 651 ) / 651

= 1 / 651

= 1

So, Greatest Common Divisor of 475, 515, 642, 651 is 1
