GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(620, 488) = 75640
GCD(620, 488) = ( 620 x 488 ) / 75640
= 620 / 488
= 620
Step2:
LCM(4, 418) = 836
GCD(4, 418) = ( 4 x 418 ) / 836
= 4 / 418
= 4
Step3:
LCM(2, 290) = 290
GCD(2, 290) = ( 2 x 290 ) / 290
= 2 / 290
= 2
So, Greatest Common Divisor of 620, 488, 418, 290 is 2
