Steps to Calculate GCD of 758, 815, 123, 391 using LCM Formula
Given numbers are 758, 815, 123, 391
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(758, 815) = 617770
GCD(758, 815) = ( 758 x 815 ) / 617770
= 758 / 815
= 758
Step2:
LCM(1, 123) = 123
GCD(1, 123) = ( 1 x 123 ) / 123
= 1 / 123
= 1
Step3:
LCM(1, 391) = 391
GCD(1, 391) = ( 1 x 391 ) / 391
= 1 / 391
= 1
So, Greatest Common Divisor of 758, 815, 123, 391 is 1
