GCD of numbers is the greatest common divisor

So, the GCD (51, 18, 63, 49) = 1.

Given numbers are 51, 18, 63, 49

The list of prime factors of all numbers are

Prime factors of 51 are 3 x 17

Prime factors of 18 are 2 x 3 x 3

Prime factors of 63 are 3 x 3 x 7

Prime factors of 49 are 7 x 7

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 51, 18, 63, 49

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

Apply this formula for all numbers.

Step1:

LCM(51, 18) = 306

GCD(51, 18) = ( 51 x 18 ) / 306

= 51 / 18

= 51

Step2:

LCM(3, 63) = 63

GCD(3, 63) = ( 3 x 63 ) / 63

= 3 / 63

= 3

Step3:

LCM(3, 49) = 147

GCD(3, 49) = ( 3 x 49 ) / 147

= 3 / 49

= 3

So, Greatest Common Divisor of 51, 18, 63, 49 is 1
