Given numbers are 458, 638, 983, 661
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(458, 638) = 146102
GCD(458, 638) = ( 458 x 638 ) / 146102
= 458 / 638
= 458
Step2:
LCM(2, 983) = 1966
GCD(2, 983) = ( 2 x 983 ) / 1966
= 2 / 983
= 2
Step3:
LCM(1, 661) = 661
GCD(1, 661) = ( 1 x 661 ) / 661
= 1 / 661
= 1
So, Greatest Common Divisor of 458, 638, 983, 661 is 1
