GCD of numbers is the greatest common divisor

So, the GCD (91, 51, 92, 15) = 1.

Given numbers are 91, 51, 92, 15

The list of prime factors of all numbers are

Prime factors of 91 are 7 x 13

Prime factors of 51 are 3 x 17

Prime factors of 92 are 2 x 2 x 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 91, 51, 92, 15

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

Apply this formula for all numbers.

Step1:

LCM(91, 51) = 4641

GCD(91, 51) = ( 91 x 51 ) / 4641

= 91 / 51

= 91

Step2:

LCM(1, 92) = 92

GCD(1, 92) = ( 1 x 92 ) / 92

= 1 / 92

= 1

Step3:

LCM(1, 15) = 15

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

= 1 / 15

= 1

So, Greatest Common Divisor of 91, 51, 92, 15 is 1
