Steps to Calculate GCD of 905, 413, 781, 605 using LCM Formula
Given numbers are 905, 413, 781, 605
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(905, 413) = 373765
GCD(905, 413) = ( 905 x 413 ) / 373765
= 905 / 413
= 905
Step2:
LCM(1, 781) = 781
GCD(1, 781) = ( 1 x 781 ) / 781
= 1 / 781
= 1
Step3:
LCM(1, 605) = 605
GCD(1, 605) = ( 1 x 605 ) / 605
= 1 / 605
= 1
So, Greatest Common Divisor of 905, 413, 781, 605 is 1
