Given numbers are 638, 961, 955, 339
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 961) = 613118
GCD(638, 961) = ( 638 x 961 ) / 613118
= 638 / 961
= 638
Step2:
LCM(1, 955) = 955
GCD(1, 955) = ( 1 x 955 ) / 955
= 1 / 955
= 1
Step3:
LCM(1, 339) = 339
GCD(1, 339) = ( 1 x 339 ) / 339
= 1 / 339
= 1
So, Greatest Common Divisor of 638, 961, 955, 339 is 1
