Steps to Calculate GCD of 782, 381, 691, 123 using LCM Formula
Given numbers are 782, 381, 691, 123
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(782, 381) = 297942
GCD(782, 381) = ( 782 x 381 ) / 297942
= 782 / 381
= 782
Step2:
LCM(1, 691) = 691
GCD(1, 691) = ( 1 x 691 ) / 691
= 1 / 691
= 1
Step3:
LCM(1, 123) = 123
GCD(1, 123) = ( 1 x 123 ) / 123
= 1 / 123
= 1
So, Greatest Common Divisor of 782, 381, 691, 123 is 1
