Given numbers are 79, 65, 30, 25

The list of prime factors of all numbers are

Prime factors of 79 are 79

Prime factors of 65 are 5 x 13

Prime factors of 30 are 2 x 3 x 5

Prime factors of 25 are 5 x 5

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

Given numbers are 79, 65, 30, 25

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

Apply this formula for all numbers.

Step1:

LCM(79, 65) = 5135

GCD(79, 65) = ( 79 x 65 ) / 5135

= 79 / 65

= 79

Step2:

LCM(1, 30) = 30

GCD(1, 30) = ( 1 x 30 ) / 30

= 1 / 30

= 1

Step3:

LCM(1, 25) = 25

GCD(1, 25) = ( 1 x 25 ) / 25

= 1 / 25

= 1

So, Greatest Common Divisor of 79, 65, 30, 25 is 1
