Steps to Calculate GCD of 408, 345, 89, 694 using LCM Formula
Given numbers are 408, 345, 89, 694
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(408, 345) = 46920
GCD(408, 345) = ( 408 x 345 ) / 46920
= 408 / 345
= 408
Step2:
LCM(3, 89) = 267
GCD(3, 89) = ( 3 x 89 ) / 267
= 3 / 89
= 3
Step3:
LCM(1, 694) = 694
GCD(1, 694) = ( 1 x 694 ) / 694
= 1 / 694
= 1
So, Greatest Common Divisor of 408, 345, 89, 694 is 1
