Given numbers are 638, 372, 903, 955
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 372) = 118668
GCD(638, 372) = ( 638 x 372 ) / 118668
= 638 / 372
= 638
Step2:
LCM(2, 903) = 1806
GCD(2, 903) = ( 2 x 903 ) / 1806
= 2 / 903
= 2
Step3:
LCM(1, 955) = 955
GCD(1, 955) = ( 1 x 955 ) / 955
= 1 / 955
= 1
So, Greatest Common Divisor of 638, 372, 903, 955 is 1
