Steps to Calculate GCD of 309, 558, 723, 247 using LCM Formula
Given numbers are 309, 558, 723, 247
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(309, 558) = 57474
GCD(309, 558) = ( 309 x 558 ) / 57474
= 309 / 558
= 309
Step2:
LCM(3, 723) = 723
GCD(3, 723) = ( 3 x 723 ) / 723
= 3 / 723
= 3
Step3:
LCM(3, 247) = 741
GCD(3, 247) = ( 3 x 247 ) / 741
= 3 / 247
= 3
So, Greatest Common Divisor of 309, 558, 723, 247 is 1
