Steps to Calculate GCD of 291, 394, 157, 447 using LCM Formula
Given numbers are 291, 394, 157, 447
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(291, 394) = 114654
GCD(291, 394) = ( 291 x 394 ) / 114654
= 291 / 394
= 291
Step2:
LCM(1, 157) = 157
GCD(1, 157) = ( 1 x 157 ) / 157
= 1 / 157
= 1
Step3:
LCM(1, 447) = 447
GCD(1, 447) = ( 1 x 447 ) / 447
= 1 / 447
= 1
So, Greatest Common Divisor of 291, 394, 157, 447 is 1
