Steps to Calculate GCD of 649, 360, 404, 645 using LCM Formula

Given numbers are 649, 360, 404, 645

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(649, 360) = 233640

GCD(649, 360) = ( 649 x 360 ) / 233640

= 649 / 360

= 649


Step2:

LCM(1, 404) = 404

GCD(1, 404) = ( 1 x 404 ) / 404

= 1 / 404

= 1


Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1


So, Greatest Common Divisor of 649, 360, 404, 645 is 1
