Given numbers are 217, 556, 373, 649
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(217, 556) = 120652
GCD(217, 556) = ( 217 x 556 ) / 120652
= 217 / 556
= 217
Step2:
LCM(1, 373) = 373
GCD(1, 373) = ( 1 x 373 ) / 373
= 1 / 373
= 1
Step3:
LCM(1, 649) = 649
GCD(1, 649) = ( 1 x 649 ) / 649
= 1 / 649
= 1
So, Greatest Common Divisor of 217, 556, 373, 649 is 1
