Given numbers are 618, 579, 774, 655
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(618, 579) = 119274
GCD(618, 579) = ( 618 x 579 ) / 119274
= 618 / 579
= 618
Step2:
LCM(3, 774) = 774
GCD(3, 774) = ( 3 x 774 ) / 774
= 3 / 774
= 3
Step3:
LCM(3, 655) = 1965
GCD(3, 655) = ( 3 x 655 ) / 1965
= 3 / 655
= 3
So, Greatest Common Divisor of 618, 579, 774, 655 is 1
