Steps to Calculate GCD of 142, 771, 305, 913 using LCM Formula
Given numbers are 142, 771, 305, 913
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(142, 771) = 109482
GCD(142, 771) = ( 142 x 771 ) / 109482
= 142 / 771
= 142
Step2:
LCM(1, 305) = 305
GCD(1, 305) = ( 1 x 305 ) / 305
= 1 / 305
= 1
Step3:
LCM(1, 913) = 913
GCD(1, 913) = ( 1 x 913 ) / 913
= 1 / 913
= 1
So, Greatest Common Divisor of 142, 771, 305, 913 is 1
