GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(657, 216) = 15768
GCD(657, 216) = ( 657 x 216 ) / 15768
= 657 / 216
= 657
Step2:
LCM(9, 989) = 8901
GCD(9, 989) = ( 9 x 989 ) / 8901
= 9 / 989
= 9
Step3:
LCM(1, 518) = 518
GCD(1, 518) = ( 1 x 518 ) / 518
= 1 / 518
= 1
So, Greatest Common Divisor of 657, 216, 989, 518 is 1
