GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(998, 994) = 496006
GCD(998, 994) = ( 998 x 994 ) / 496006
= 998 / 994
= 998
Step2:
LCM(2, 650) = 650
GCD(2, 650) = ( 2 x 650 ) / 650
= 2 / 650
= 2
Step3:
LCM(2, 648) = 648
GCD(2, 648) = ( 2 x 648 ) / 648
= 2 / 648
= 2
So, Greatest Common Divisor of 998, 994, 650, 648 is 2
