Given numbers are 861, 777, 728, 962

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 777 are 3 x 7 x 37

Prime factors of 728 are 2 x 2 x 2 x 7 x 13

Prime factors of 962 are 2 x 13 x 37

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

Given numbers are 861, 777, 728, 962

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

Apply this formula for all numbers.

Step1:

LCM(861, 777) = 31857

GCD(861, 777) = ( 861 x 777 ) / 31857

= 861 / 777

= 861

Step2:

LCM(21, 728) = 2184

GCD(21, 728) = ( 21 x 728 ) / 2184

= 21 / 728

= 21

Step3:

LCM(7, 962) = 6734

GCD(7, 962) = ( 7 x 962 ) / 6734

= 7 / 962

= 7

So, Greatest Common Divisor of 861, 777, 728, 962 is 1
