Given numbers are 404, 688, 615, 672

The list of prime factors of all numbers are

Prime factors of 404 are 2 x 2 x 101

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

Prime factors of 615 are 3 x 5 x 41

Prime factors of 672 are 2 x 2 x 2 x 2 x 2 x 3 x 7

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

Given numbers are 404, 688, 615, 672

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

Apply this formula for all numbers.

Step1:

LCM(404, 688) = 69488

GCD(404, 688) = ( 404 x 688 ) / 69488

= 404 / 688

= 404

Step2:

LCM(4, 615) = 2460

GCD(4, 615) = ( 4 x 615 ) / 2460

= 4 / 615

= 4

Step3:

LCM(1, 672) = 672

GCD(1, 672) = ( 1 x 672 ) / 672

= 1 / 672

= 1

So, Greatest Common Divisor of 404, 688, 615, 672 is 1
