Steps to Calculate GCD of 142, 331, 81, 585 using LCM Formula
Given numbers are 142, 331, 81, 585
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(142, 331) = 47002
GCD(142, 331) = ( 142 x 331 ) / 47002
= 142 / 331
= 142
Step2:
LCM(1, 81) = 81
GCD(1, 81) = ( 1 x 81 ) / 81
= 1 / 81
= 1
Step3:
LCM(1, 585) = 585
GCD(1, 585) = ( 1 x 585 ) / 585
= 1 / 585
= 1
So, Greatest Common Divisor of 142, 331, 81, 585 is 1
