Given numbers are 400, 643, 912

The list of prime factors of all numbers are

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

Prime factors of 643 are 643

Prime factors of 912 are 2 x 2 x 2 x 2 x 3 x 19

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

Given numbers are 400, 643, 912

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

Apply this formula for all numbers.

Step1:

LCM(400, 643) = 257200

GCD(400, 643) = ( 400 x 643 ) / 257200

= 400 / 643

= 400

Step2:

LCM(1, 912) = 912

GCD(1, 912) = ( 1 x 912 ) / 912

= 1 / 912

= 1

So, Greatest Common Divisor of 400, 643, 912 is 1
