Given numbers are 991, 756, 858, 365

The list of prime factors of all numbers are

Prime factors of 991 are 991

Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7

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

Prime factors of 365 are 5 x 73

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

Given numbers are 991, 756, 858, 365

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

Apply this formula for all numbers.

Step1:

LCM(991, 756) = 749196

GCD(991, 756) = ( 991 x 756 ) / 749196

= 991 / 756

= 991

Step2:

LCM(1, 858) = 858

GCD(1, 858) = ( 1 x 858 ) / 858

= 1 / 858

= 1

Step3:

LCM(1, 365) = 365

GCD(1, 365) = ( 1 x 365 ) / 365

= 1 / 365

= 1

So, Greatest Common Divisor of 991, 756, 858, 365 is 1
