Steps to Calculate GCD of 247, 209, 31, 314 using LCM Formula
Given numbers are 247, 209, 31, 314
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(247, 209) = 2717
GCD(247, 209) = ( 247 x 209 ) / 2717
= 247 / 209
= 247
Step2:
LCM(19, 31) = 589
GCD(19, 31) = ( 19 x 31 ) / 589
= 19 / 31
= 19
Step3:
LCM(1, 314) = 314
GCD(1, 314) = ( 1 x 314 ) / 314
= 1 / 314
= 1
So, Greatest Common Divisor of 247, 209, 31, 314 is 1
