Given numbers are 636, 435, 400, 663

The list of prime factors of all numbers are

Prime factors of 636 are 2 x 2 x 3 x 53

Prime factors of 435 are 3 x 5 x 29

Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 663 are 3 x 13 x 17

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

Given numbers are 636, 435, 400, 663

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

Apply this formula for all numbers.

Step1:

LCM(636, 435) = 92220

GCD(636, 435) = ( 636 x 435 ) / 92220

= 636 / 435

= 636

Step2:

LCM(3, 400) = 1200

GCD(3, 400) = ( 3 x 400 ) / 1200

= 3 / 400

= 3

Step3:

LCM(1, 663) = 663

GCD(1, 663) = ( 1 x 663 ) / 663

= 1 / 663

= 1

So, Greatest Common Divisor of 636, 435, 400, 663 is 1
