Given numbers are 638, 682, 154, 511
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 682) = 19778
GCD(638, 682) = ( 638 x 682 ) / 19778
= 638 / 682
= 638
Step2:
LCM(22, 154) = 154
GCD(22, 154) = ( 22 x 154 ) / 154
= 22 / 154
= 22
Step3:
LCM(22, 511) = 11242
GCD(22, 511) = ( 22 x 511 ) / 11242
= 22 / 511
= 22
So, Greatest Common Divisor of 638, 682, 154, 511 is 1
