Given numbers are 315, 640, 77, 435

The list of prime factors of all numbers are

Prime factors of 315 are 3 x 3 x 5 x 7

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

Prime factors of 77 are 7 x 11

Prime factors of 435 are 3 x 5 x 29

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

Given numbers are 315, 640, 77, 435

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

Apply this formula for all numbers.

Step1:

LCM(315, 640) = 40320

GCD(315, 640) = ( 315 x 640 ) / 40320

= 315 / 640

= 315

Step2:

LCM(5, 77) = 385

GCD(5, 77) = ( 5 x 77 ) / 385

= 5 / 77

= 5

Step3:

LCM(1, 435) = 435

GCD(1, 435) = ( 1 x 435 ) / 435

= 1 / 435

= 1

So, Greatest Common Divisor of 315, 640, 77, 435 is 1
