Steps to Calculate GCD of 664, 342, 13, 990 using LCM Formula

Given numbers are 664, 342, 13, 990

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

Apply this formula for all numbers.

Step1:

LCM(664, 342) = 113544

GCD(664, 342) = ( 664 x 342 ) / 113544

= 664 / 342

= 664


Step2:

LCM(2, 13) = 26

GCD(2, 13) = ( 2 x 13 ) / 26

= 2 / 13

= 2


Step3:

LCM(1, 990) = 990

GCD(1, 990) = ( 1 x 990 ) / 990

= 1 / 990

= 1


So, Greatest Common Divisor of 664, 342, 13, 990 is 1
