Given numbers are 638, 272, 687, 767
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 272) = 86768
GCD(638, 272) = ( 638 x 272 ) / 86768
= 638 / 272
= 638
Step2:
LCM(2, 687) = 1374
GCD(2, 687) = ( 2 x 687 ) / 1374
= 2 / 687
= 2
Step3:
LCM(1, 767) = 767
GCD(1, 767) = ( 1 x 767 ) / 767
= 1 / 767
= 1
So, Greatest Common Divisor of 638, 272, 687, 767 is 1
