Given numbers are 861, 385, 554, 651

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 385 are 5 x 7 x 11

Prime factors of 554 are 2 x 277

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 861, 385, 554, 651

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

Apply this formula for all numbers.

Step1:

LCM(861, 385) = 47355

GCD(861, 385) = ( 861 x 385 ) / 47355

= 861 / 385

= 861

Step2:

LCM(7, 554) = 3878

GCD(7, 554) = ( 7 x 554 ) / 3878

= 7 / 554

= 7

Step3:

LCM(1, 651) = 651

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

= 1 / 651

= 1

So, Greatest Common Divisor of 861, 385, 554, 651 is 1
