GCD of numbers is the greatest common divisor

So, the GCD (73, 15, 87, 56) = 1.

Given numbers are 73, 15, 87, 56

The list of prime factors of all numbers are

Prime factors of 73 are 73

Prime factors of 15 are 3 x 5

Prime factors of 87 are 3 x 29

Prime factors of 56 are 2 x 2 x 2 x 7

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

Given numbers are 73, 15, 87, 56

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

Apply this formula for all numbers.

Step1:

LCM(73, 15) = 1095

GCD(73, 15) = ( 73 x 15 ) / 1095

= 73 / 15

= 73

Step2:

LCM(1, 87) = 87

GCD(1, 87) = ( 1 x 87 ) / 87

= 1 / 87

= 1

Step3:

LCM(1, 56) = 56

GCD(1, 56) = ( 1 x 56 ) / 56

= 1 / 56

= 1

So, Greatest Common Divisor of 73, 15, 87, 56 is 1
