GCD of numbers is the greatest common divisor

So, the GCD (19, 40, 61, 24) = 1.

Given numbers are 19, 40, 61, 24

The list of prime factors of all numbers are

Prime factors of 19 are 19

Prime factors of 40 are 2 x 2 x 2 x 5

Prime factors of 61 are 61

Prime factors of 24 are 2 x 2 x 2 x 3

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

Given numbers are 19, 40, 61, 24

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

Apply this formula for all numbers.

Step1:

LCM(19, 40) = 760

GCD(19, 40) = ( 19 x 40 ) / 760

= 19 / 40

= 19

Step2:

LCM(1, 61) = 61

GCD(1, 61) = ( 1 x 61 ) / 61

= 1 / 61

= 1

Step3:

LCM(1, 24) = 24

GCD(1, 24) = ( 1 x 24 ) / 24

= 1 / 24

= 1

So, Greatest Common Divisor of 19, 40, 61, 24 is 1
