Given numbers are 969, 720, 858, 658

The list of prime factors of all numbers are

Prime factors of 969 are 3 x 17 x 19

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 858 are 2 x 3 x 11 x 13

Prime factors of 658 are 2 x 7 x 47

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

Given numbers are 969, 720, 858, 658

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

Apply this formula for all numbers.

Step1:

LCM(969, 720) = 232560

GCD(969, 720) = ( 969 x 720 ) / 232560

= 969 / 720

= 969

Step2:

LCM(3, 858) = 858

GCD(3, 858) = ( 3 x 858 ) / 858

= 3 / 858

= 3

Step3:

LCM(3, 658) = 1974

GCD(3, 658) = ( 3 x 658 ) / 1974

= 3 / 658

= 3

So, Greatest Common Divisor of 969, 720, 858, 658 is 1
