Given numbers are 218, 421, 102, 556
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(218, 421) = 91778
GCD(218, 421) = ( 218 x 421 ) / 91778
= 218 / 421
= 218
Step2:
LCM(1, 102) = 102
GCD(1, 102) = ( 1 x 102 ) / 102
= 1 / 102
= 1
Step3:
LCM(1, 556) = 556
GCD(1, 556) = ( 1 x 556 ) / 556
= 1 / 556
= 1
So, Greatest Common Divisor of 218, 421, 102, 556 is 1
