Given numbers are 638, 725, 719, 211

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

Apply this formula for all numbers.

Step1:

LCM(638, 725) = 15950

GCD(638, 725) = ( 638 x 725 ) / 15950

= 638 / 725

= 638

Step2:

LCM(29, 719) = 20851

GCD(29, 719) = ( 29 x 719 ) / 20851

= 29 / 719

= 29

Step3:

LCM(1, 211) = 211

GCD(1, 211) = ( 1 x 211 ) / 211

= 1 / 211

= 1

So, Greatest Common Divisor of 638, 725, 719, 211 is 1
