GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(420, 606) = 42420
GCD(420, 606) = ( 420 x 606 ) / 42420
= 420 / 606
= 420
Step2:
LCM(6, 316) = 948
GCD(6, 316) = ( 6 x 316 ) / 948
= 6 / 316
= 6
Step3:
LCM(2, 120) = 120
GCD(2, 120) = ( 2 x 120 ) / 120
= 2 / 120
= 2
So, Greatest Common Divisor of 420, 606, 316, 120 is 2
