Steps to Calculate GCD of 49, 23, 14, 42 using LCM Formula

Given numbers are 49, 23, 14, 42

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

Apply this formula for all numbers.

Step1:

LCM(49, 23) = 1127

GCD(49, 23) = ( 49 x 23 ) / 1127

= 49 / 23

= 49


Step2:

LCM(1, 14) = 14

GCD(1, 14) = ( 1 x 14 ) / 14

= 1 / 14

= 1


Step3:

LCM(1, 42) = 42

GCD(1, 42) = ( 1 x 42 ) / 42

= 1 / 42

= 1


So, Greatest Common Divisor of 49, 23, 14, 42 is 1
