Given numbers are 651, 198, 72, 430

The list of prime factors of all numbers are

Prime factors of 651 are 3 x 7 x 31

Prime factors of 198 are 2 x 3 x 3 x 11

Prime factors of 72 are 2 x 2 x 2 x 3 x 3

Prime factors of 430 are 2 x 5 x 43

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

Given numbers are 651, 198, 72, 430

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

Apply this formula for all numbers.

Step1:

LCM(651, 198) = 42966

GCD(651, 198) = ( 651 x 198 ) / 42966

= 651 / 198

= 651

Step2:

LCM(3, 72) = 72

GCD(3, 72) = ( 3 x 72 ) / 72

= 3 / 72

= 3

Step3:

LCM(3, 430) = 1290

GCD(3, 430) = ( 3 x 430 ) / 1290

= 3 / 430

= 3

So, Greatest Common Divisor of 651, 198, 72, 430 is 1
