GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(122, 556) = 33916
GCD(122, 556) = ( 122 x 556 ) / 33916
= 122 / 556
= 122
Step2:
LCM(2, 282) = 282
GCD(2, 282) = ( 2 x 282 ) / 282
= 2 / 282
= 2
Step3:
LCM(2, 630) = 630
GCD(2, 630) = ( 2 x 630 ) / 630
= 2 / 630
= 2
So, Greatest Common Divisor of 122, 556, 282, 630 is 2
