Given numbers are 218, 682, 420, 577
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(218, 682) = 74338
GCD(218, 682) = ( 218 x 682 ) / 74338
= 218 / 682
= 218
Step2:
LCM(2, 420) = 420
GCD(2, 420) = ( 2 x 420 ) / 420
= 2 / 420
= 2
Step3:
LCM(2, 577) = 1154
GCD(2, 577) = ( 2 x 577 ) / 1154
= 2 / 577
= 2
So, Greatest Common Divisor of 218, 682, 420, 577 is 1
