GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(255, 664) = 169320
GCD(255, 664) = ( 255 x 664 ) / 169320
= 255 / 664
= 255
Step2:
LCM(1, 549) = 549
GCD(1, 549) = ( 1 x 549 ) / 549
= 1 / 549
= 1
Step3:
LCM(1, 816) = 816
GCD(1, 816) = ( 1 x 816 ) / 816
= 1 / 816
= 1
So, Greatest Common Divisor of 255, 664, 549, 816 is 1
