Given numbers are 400, 642, 633, 778

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 642 are 2 x 3 x 107

Prime factors of 633 are 3 x 211

Prime factors of 778 are 2 x 389

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

Given numbers are 400, 642, 633, 778

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

Apply this formula for all numbers.

Step1:

LCM(400, 642) = 128400

GCD(400, 642) = ( 400 x 642 ) / 128400

= 400 / 642

= 400

Step2:

LCM(2, 633) = 1266

GCD(2, 633) = ( 2 x 633 ) / 1266

= 2 / 633

= 2

Step3:

LCM(1, 778) = 778

GCD(1, 778) = ( 1 x 778 ) / 778

= 1 / 778

= 1

So, Greatest Common Divisor of 400, 642, 633, 778 is 1
