Given numbers are 891, 732, 736, 646

The list of prime factors of all numbers are

Prime factors of 891 are 3 x 3 x 3 x 3 x 11

Prime factors of 732 are 2 x 2 x 3 x 61

Prime factors of 736 are 2 x 2 x 2 x 2 x 2 x 23

Prime factors of 646 are 2 x 17 x 19

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

Given numbers are 891, 732, 736, 646

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

Apply this formula for all numbers.

Step1:

LCM(891, 732) = 217404

GCD(891, 732) = ( 891 x 732 ) / 217404

= 891 / 732

= 891

Step2:

LCM(3, 736) = 2208

GCD(3, 736) = ( 3 x 736 ) / 2208

= 3 / 736

= 3

Step3:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

So, Greatest Common Divisor of 891, 732, 736, 646 is 1
