Steps to Calculate GCD of 247, 668, 163, 481 using LCM Formula
Given numbers are 247, 668, 163, 481
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(247, 668) = 164996
GCD(247, 668) = ( 247 x 668 ) / 164996
= 247 / 668
= 247
Step2:
LCM(1, 163) = 163
GCD(1, 163) = ( 1 x 163 ) / 163
= 1 / 163
= 1
Step3:
LCM(1, 481) = 481
GCD(1, 481) = ( 1 x 481 ) / 481
= 1 / 481
= 1
So, Greatest Common Divisor of 247, 668, 163, 481 is 1
