GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(156, 822) = 21372
GCD(156, 822) = ( 156 x 822 ) / 21372
= 156 / 822
= 156
Step2:
LCM(6, 481) = 2886
GCD(6, 481) = ( 6 x 481 ) / 2886
= 6 / 481
= 6
Step3:
LCM(1, 220) = 220
GCD(1, 220) = ( 1 x 220 ) / 220
= 1 / 220
= 1
So, Greatest Common Divisor of 156, 822, 481, 220 is 1
