GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(960, 700) = 33600
GCD(960, 700) = ( 960 x 700 ) / 33600
= 960 / 700
= 960
Step2:
LCM(20, 420) = 420
GCD(20, 420) = ( 20 x 420 ) / 420
= 20 / 420
= 20
So, Greatest Common Divisor of 960, 700, 420 is 20
