Given numbers are 638, 240, 713, 456

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 240 are 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 713 are 23 x 31

Prime factors of 456 are 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 638, 240, 713, 456

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

Apply this formula for all numbers.

Step1:

LCM(638, 240) = 76560

GCD(638, 240) = ( 638 x 240 ) / 76560

= 638 / 240

= 638

Step2:

LCM(2, 713) = 1426

GCD(2, 713) = ( 2 x 713 ) / 1426

= 2 / 713

= 2

Step3:

LCM(1, 456) = 456

GCD(1, 456) = ( 1 x 456 ) / 456

= 1 / 456

= 1

So, Greatest Common Divisor of 638, 240, 713, 456 is 1
