Steps to Calculate GCD of 789, 714, 155, 845 using LCM Formula
Given numbers are 789, 714, 155, 845
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(789, 714) = 187782
GCD(789, 714) = ( 789 x 714 ) / 187782
= 789 / 714
= 789
Step2:
LCM(3, 155) = 465
GCD(3, 155) = ( 3 x 155 ) / 465
= 3 / 155
= 3
Step3:
LCM(1, 845) = 845
GCD(1, 845) = ( 1 x 845 ) / 845
= 1 / 845
= 1
So, Greatest Common Divisor of 789, 714, 155, 845 is 1
