Steps to Calculate GCD of 618, 391, 123, 603 using LCM Formula
Given numbers are 618, 391, 123, 603
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(618, 391) = 241638
GCD(618, 391) = ( 618 x 391 ) / 241638
= 618 / 391
= 618
Step2:
LCM(1, 123) = 123
GCD(1, 123) = ( 1 x 123 ) / 123
= 1 / 123
= 1
Step3:
LCM(1, 603) = 603
GCD(1, 603) = ( 1 x 603 ) / 603
= 1 / 603
= 1
So, Greatest Common Divisor of 618, 391, 123, 603 is 1
