Given numbers are 865, 121, 472, 147

The list of prime factors of all numbers are

Prime factors of 865 are 5 x 173

Prime factors of 121 are 11 x 11

Prime factors of 472 are 2 x 2 x 2 x 59

Prime factors of 147 are 3 x 7 x 7

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

Given numbers are 865, 121, 472, 147

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

Apply this formula for all numbers.

Step1:

LCM(865, 121) = 104665

GCD(865, 121) = ( 865 x 121 ) / 104665

= 865 / 121

= 865

Step2:

LCM(1, 472) = 472

GCD(1, 472) = ( 1 x 472 ) / 472

= 1 / 472

= 1

Step3:

LCM(1, 147) = 147

GCD(1, 147) = ( 1 x 147 ) / 147

= 1 / 147

= 1

So, Greatest Common Divisor of 865, 121, 472, 147 is 1
