GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(620, 444) = 68820
GCD(620, 444) = ( 620 x 444 ) / 68820
= 620 / 444
= 620
Step2:
LCM(4, 242) = 484
GCD(4, 242) = ( 4 x 242 ) / 484
= 4 / 242
= 4
Step3:
LCM(2, 480) = 480
GCD(2, 480) = ( 2 x 480 ) / 480
= 2 / 480
= 2
So, Greatest Common Divisor of 620, 444, 242, 480 is 2
