Given numbers are 638, 656, 719, 711

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

Apply this formula for all numbers.

Step1:

LCM(638, 656) = 209264

GCD(638, 656) = ( 638 x 656 ) / 209264

= 638 / 656

= 638

Step2:

LCM(2, 719) = 1438

GCD(2, 719) = ( 2 x 719 ) / 1438

= 2 / 719

= 2

Step3:

LCM(1, 711) = 711

GCD(1, 711) = ( 1 x 711 ) / 711

= 1 / 711

= 1

So, Greatest Common Divisor of 638, 656, 719, 711 is 1
