GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(392, 208) = 10192
GCD(392, 208) = ( 392 x 208 ) / 10192
= 392 / 208
= 392
Step2:
LCM(8, 677) = 5416
GCD(8, 677) = ( 8 x 677 ) / 5416
= 8 / 677
= 8
Step3:
LCM(1, 870) = 870
GCD(1, 870) = ( 1 x 870 ) / 870
= 1 / 870
= 1
So, Greatest Common Divisor of 392, 208, 677, 870 is 1
