1, 3, 7, 21

Divisors of 58 :

The positive integer divisors of 58 that completely divides 58 are.

1, 2, 29, 58

Divisors of 61 :

The positive integer divisors of 61 that completely divides 61 are.

1, 61

Divisors of 24 :

The positive integer divisors of 24 that completely divides 24 are.

1, 2, 3, 4, 6, 8, 12, 24

GCD of numbers is the greatest common divisor

So, the GCD (21, 58, 61, 24) = 1.

Given numbers are 21, 58, 61, 24

The list of prime factors of all numbers are

Prime factors of 21 are 3 x 7

Prime factors of 58 are 2 x 29

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 21, 58, 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(21, 58) = 1218

GCD(21, 58) = ( 21 x 58 ) / 1218

= 21 / 58

= 21

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 21, 58, 61, 24 is 1
