GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(870, 972) = 140940
GCD(870, 972) = ( 870 x 972 ) / 140940
= 870 / 972
= 870
Step2:
LCM(6, 407) = 2442
GCD(6, 407) = ( 6 x 407 ) / 2442
= 6 / 407
= 6
So, Greatest Common Divisor of 870, 972, 407 is 1
