GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(633, 561) = 118371
GCD(633, 561) = ( 633 x 561 ) / 118371
= 633 / 561
= 633
Step2:
LCM(3, 768) = 768
GCD(3, 768) = ( 3 x 768 ) / 768
= 3 / 768
= 3
Step3:
LCM(3, 218) = 654
GCD(3, 218) = ( 3 x 218 ) / 654
= 3 / 218
= 3
So, Greatest Common Divisor of 633, 561, 768, 218 is 1
