Steps to Calculate GCD of 635, 408, 23, 649 using LCM Formula

Given numbers are 635, 408, 23, 649

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

Apply this formula for all numbers.

Step1:

LCM(635, 408) = 259080

GCD(635, 408) = ( 635 x 408 ) / 259080

= 635 / 408

= 635


Step2:

LCM(1, 23) = 23

GCD(1, 23) = ( 1 x 23 ) / 23

= 1 / 23

= 1


Step3:

LCM(1, 649) = 649

GCD(1, 649) = ( 1 x 649 ) / 649

= 1 / 649

= 1


So, Greatest Common Divisor of 635, 408, 23, 649 is 1
