Steps to Calculate GCD of 647, 623, 665, 353 using LCM Formula
Given numbers are 647, 623, 665, 353
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(647, 623) = 403081
GCD(647, 623) = ( 647 x 623 ) / 403081
= 647 / 623
= 647
Step2:
LCM(1, 665) = 665
GCD(1, 665) = ( 1 x 665 ) / 665
= 1 / 665
= 1
Step3:
LCM(1, 353) = 353
GCD(1, 353) = ( 1 x 353 ) / 353
= 1 / 353
= 1
So, Greatest Common Divisor of 647, 623, 665, 353 is 1
