Given numbers are 357, 732, 640, 805

The list of prime factors of all numbers are

Prime factors of 357 are 3 x 7 x 17

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

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 805 are 5 x 7 x 23

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

Given numbers are 357, 732, 640, 805

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

Apply this formula for all numbers.

Step1:

LCM(357, 732) = 87108

GCD(357, 732) = ( 357 x 732 ) / 87108

= 357 / 732

= 357

Step2:

LCM(3, 640) = 1920

GCD(3, 640) = ( 3 x 640 ) / 1920

= 3 / 640

= 3

Step3:

LCM(1, 805) = 805

GCD(1, 805) = ( 1 x 805 ) / 805

= 1 / 805

= 1

So, Greatest Common Divisor of 357, 732, 640, 805 is 1
