GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(354, 711) = 83898
GCD(354, 711) = ( 354 x 711 ) / 83898
= 354 / 711
= 354
Step2:
LCM(3, 870) = 870
GCD(3, 870) = ( 3 x 870 ) / 870
= 3 / 870
= 3
Step3:
LCM(3, 861) = 861
GCD(3, 861) = ( 3 x 861 ) / 861
= 3 / 861
= 3
So, Greatest Common Divisor of 354, 711, 870, 861 is 3
