Steps to Calculate GCD of 618, 309, 25, 289 using LCM Formula
Given numbers are 618, 309, 25, 289
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(618, 309) = 618
GCD(618, 309) = ( 618 x 309 ) / 618
= 618 / 309
= 618
Step2:
LCM(309, 25) = 7725
GCD(309, 25) = ( 309 x 25 ) / 7725
= 309 / 25
= 309
Step3:
LCM(1, 289) = 289
GCD(1, 289) = ( 1 x 289 ) / 289
= 1 / 289
= 1
So, Greatest Common Divisor of 618, 309, 25, 289 is 1
