1, 3, 5, 15

GCD of numbers is the greatest common divisor

So, the GCD (10, 63, 23, 15) = 1.

Given numbers are 10, 63, 23, 15

The list of prime factors of all numbers are

Prime factors of 10 are 2 x 5

Prime factors of 63 are 3 x 3 x 7

Prime factors of 23 are 23

Prime factors of 15 are 3 x 5

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

Given numbers are 10, 63, 23, 15

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

Apply this formula for all numbers.

Step1:

LCM(10, 63) = 630

GCD(10, 63) = ( 10 x 63 ) / 630

= 10 / 63

= 10

Step2:

LCM(1, 23) = 23

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

= 1 / 23

= 1

Step3:

LCM(1, 15) = 15

GCD(1, 15) = ( 1 x 15 ) / 15

= 1 / 15

= 1

So, Greatest Common Divisor of 10, 63, 23, 15 is 1
