Given numbers are 965, 334, 816, 642

The list of prime factors of all numbers are

Prime factors of 965 are 5 x 193

Prime factors of 334 are 2 x 167

Prime factors of 816 are 2 x 2 x 2 x 2 x 3 x 17

Prime factors of 642 are 2 x 3 x 107

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

Given numbers are 965, 334, 816, 642

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

Apply this formula for all numbers.

Step1:

LCM(965, 334) = 322310

GCD(965, 334) = ( 965 x 334 ) / 322310

= 965 / 334

= 965

Step2:

LCM(1, 816) = 816

GCD(1, 816) = ( 1 x 816 ) / 816

= 1 / 816

= 1

Step3:

LCM(1, 642) = 642

GCD(1, 642) = ( 1 x 642 ) / 642

= 1 / 642

= 1

So, Greatest Common Divisor of 965, 334, 816, 642 is 1
