Steps to Calculate GCD of 785, 605, 556, 748 using LCM Formula
Given numbers are 785, 605, 556, 748
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(785, 605) = 94985
GCD(785, 605) = ( 785 x 605 ) / 94985
= 785 / 605
= 785
Step2:
LCM(5, 556) = 2780
GCD(5, 556) = ( 5 x 556 ) / 2780
= 5 / 556
= 5
Step3:
LCM(1, 748) = 748
GCD(1, 748) = ( 1 x 748 ) / 748
= 1 / 748
= 1
So, Greatest Common Divisor of 785, 605, 556, 748 is 1
