Given numbers are 674, 681, 632, 420
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(674, 681) = 458994
GCD(674, 681) = ( 674 x 681 ) / 458994
= 674 / 681
= 674
Step2:
LCM(1, 632) = 632
GCD(1, 632) = ( 1 x 632 ) / 632
= 1 / 632
= 1
Step3:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
So, Greatest Common Divisor of 674, 681, 632, 420 is 1
