Given numbers are 638, 669, 451

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

Apply this formula for all numbers.

Step1:

LCM(638, 669) = 426822

GCD(638, 669) = ( 638 x 669 ) / 426822

= 638 / 669

= 638

Step2:

LCM(1, 451) = 451

GCD(1, 451) = ( 1 x 451 ) / 451

= 1 / 451

= 1

So, Greatest Common Divisor of 638, 669, 451 is 1
