Steps to Calculate GCD of 154, 343, 563, 791 using LCM Formula
Given numbers are 154, 343, 563, 791
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(154, 343) = 7546
GCD(154, 343) = ( 154 x 343 ) / 7546
= 154 / 343
= 154
Step2:
LCM(7, 563) = 3941
GCD(7, 563) = ( 7 x 563 ) / 3941
= 7 / 563
= 7
Step3:
LCM(1, 791) = 791
GCD(1, 791) = ( 1 x 791 ) / 791
= 1 / 791
= 1
So, Greatest Common Divisor of 154, 343, 563, 791 is 1
