Given numbers are 665, 638, 56

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

Apply this formula for all numbers.

Step1:

LCM(665, 638) = 424270

GCD(665, 638) = ( 665 x 638 ) / 424270

= 665 / 638

= 665

Step2:

LCM(1, 56) = 56

GCD(1, 56) = ( 1 x 56 ) / 56

= 1 / 56

= 1

So, Greatest Common Divisor of 665, 638, 56 is 1
