Steps to Calculate GCD of 523, 247, 45, 538 using LCM Formula
Given numbers are 523, 247, 45, 538
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(523, 247) = 129181
GCD(523, 247) = ( 523 x 247 ) / 129181
= 523 / 247
= 523
Step2:
LCM(1, 45) = 45
GCD(1, 45) = ( 1 x 45 ) / 45
= 1 / 45
= 1
Step3:
LCM(1, 538) = 538
GCD(1, 538) = ( 1 x 538 ) / 538
= 1 / 538
= 1
So, Greatest Common Divisor of 523, 247, 45, 538 is 1
