GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(620, 678) = 210180
GCD(620, 678) = ( 620 x 678 ) / 210180
= 620 / 678
= 620
Step2:
LCM(2, 430) = 430
GCD(2, 430) = ( 2 x 430 ) / 430
= 2 / 430
= 2
Step3:
LCM(2, 518) = 518
GCD(2, 518) = ( 2 x 518 ) / 518
= 2 / 518
= 2
So, Greatest Common Divisor of 620, 678, 430, 518 is 2
