Steps to Calculate GCD of 746, 631, 65, 405 using LCM Formula
Given numbers are 746, 631, 65, 405
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(746, 631) = 470726
GCD(746, 631) = ( 746 x 631 ) / 470726
= 746 / 631
= 746
Step2:
LCM(1, 65) = 65
GCD(1, 65) = ( 1 x 65 ) / 65
= 1 / 65
= 1
Step3:
LCM(1, 405) = 405
GCD(1, 405) = ( 1 x 405 ) / 405
= 1 / 405
= 1
So, Greatest Common Divisor of 746, 631, 65, 405 is 1
