Given numbers are 462, 421, 208, 681
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(462, 421) = 194502
GCD(462, 421) = ( 462 x 421 ) / 194502
= 462 / 421
= 462
Step2:
LCM(1, 208) = 208
GCD(1, 208) = ( 1 x 208 ) / 208
= 1 / 208
= 1
Step3:
LCM(1, 681) = 681
GCD(1, 681) = ( 1 x 681 ) / 681
= 1 / 681
= 1
So, Greatest Common Divisor of 462, 421, 208, 681 is 1
