Steps to Calculate GCD of 663, 126, 743, 385 using LCM Formula
Given numbers are 663, 126, 743, 385
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(663, 126) = 27846
GCD(663, 126) = ( 663 x 126 ) / 27846
= 663 / 126
= 663
Step2:
LCM(3, 743) = 2229
GCD(3, 743) = ( 3 x 743 ) / 2229
= 3 / 743
= 3
Step3:
LCM(1, 385) = 385
GCD(1, 385) = ( 1 x 385 ) / 385
= 1 / 385
= 1
So, Greatest Common Divisor of 663, 126, 743, 385 is 1
