Given numbers are 961, 849, 972, 620

The list of prime factors of all numbers are

Prime factors of 961 are 31 x 31

Prime factors of 849 are 3 x 283

Prime factors of 972 are 2 x 2 x 3 x 3 x 3 x 3 x 3

Prime factors of 620 are 2 x 2 x 5 x 31

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

Given numbers are 961, 849, 972, 620

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

Apply this formula for all numbers.

Step1:

LCM(961, 849) = 815889

GCD(961, 849) = ( 961 x 849 ) / 815889

= 961 / 849

= 961

Step2:

LCM(1, 972) = 972

GCD(1, 972) = ( 1 x 972 ) / 972

= 1 / 972

= 1

Step3:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

So, Greatest Common Divisor of 961, 849, 972, 620 is 1
