Given numbers are 438, 932, 765, 651

The list of prime factors of all numbers are

Prime factors of 438 are 2 x 3 x 73

Prime factors of 932 are 2 x 2 x 233

Prime factors of 765 are 3 x 3 x 5 x 17

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 438, 932, 765, 651

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

Apply this formula for all numbers.

Step1:

LCM(438, 932) = 204108

GCD(438, 932) = ( 438 x 932 ) / 204108

= 438 / 932

= 438

Step2:

LCM(2, 765) = 1530

GCD(2, 765) = ( 2 x 765 ) / 1530

= 2 / 765

= 2

Step3:

LCM(1, 651) = 651

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

= 1 / 651

= 1

So, Greatest Common Divisor of 438, 932, 765, 651 is 1
