GCD of numbers is the greatest common divisor

So, the GCD (68, 67, 75, 25) = 1.

Given numbers are 68, 67, 75, 25

The list of prime factors of all numbers are

Prime factors of 68 are 2 x 2 x 17

Prime factors of 67 are 67

Prime factors of 75 are 3 x 5 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 68, 67, 75, 25

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

Apply this formula for all numbers.

Step1:

LCM(68, 67) = 4556

GCD(68, 67) = ( 68 x 67 ) / 4556

= 68 / 67

= 68

Step2:

LCM(1, 75) = 75

GCD(1, 75) = ( 1 x 75 ) / 75

= 1 / 75

= 1

Step3:

LCM(1, 25) = 25

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

= 1 / 25

= 1

So, Greatest Common Divisor of 68, 67, 75, 25 is 1
