Given numbers are 572, 651, 855, 781

The list of prime factors of all numbers are

Prime factors of 572 are 2 x 2 x 11 x 13

Prime factors of 651 are 3 x 7 x 31

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 781 are 11 x 71

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

Given numbers are 572, 651, 855, 781

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

Apply this formula for all numbers.

Step1:

LCM(572, 651) = 372372

GCD(572, 651) = ( 572 x 651 ) / 372372

= 572 / 651

= 572

Step2:

LCM(1, 855) = 855

GCD(1, 855) = ( 1 x 855 ) / 855

= 1 / 855

= 1

Step3:

LCM(1, 781) = 781

GCD(1, 781) = ( 1 x 781 ) / 781

= 1 / 781

= 1

So, Greatest Common Divisor of 572, 651, 855, 781 is 1
