Given numbers are 630, 994, 421, 681
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(630, 994) = 44730
GCD(630, 994) = ( 630 x 994 ) / 44730
= 630 / 994
= 630
Step2:
LCM(14, 421) = 5894
GCD(14, 421) = ( 14 x 421 ) / 5894
= 14 / 421
= 14
Step3:
LCM(1, 681) = 681
GCD(1, 681) = ( 1 x 681 ) / 681
= 1 / 681
= 1
So, Greatest Common Divisor of 630, 994, 421, 681 is 1
