Given numbers are 681, 870, 572, 420
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(681, 870) = 197490
GCD(681, 870) = ( 681 x 870 ) / 197490
= 681 / 870
= 681
Step2:
LCM(3, 572) = 1716
GCD(3, 572) = ( 3 x 572 ) / 1716
= 3 / 572
= 3
Step3:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
So, Greatest Common Divisor of 681, 870, 572, 420 is 1
