Given numbers are 50, 42, 20, 84
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(50, 42) = 1050
GCD(50, 42) = ( 50 x 42 ) / 1050
= 50 / 42
= 50
Step2:
LCM(2, 20) = 20
GCD(2, 20) = ( 2 x 20 ) / 20
= 2 / 20
= 2
Step3:
LCM(2, 84) = 84
GCD(2, 84) = ( 2 x 84 ) / 84
= 2 / 84
= 2
So, Greatest Common Divisor of 50, 42, 20, 84 is 2
