Given numbers are 86, 38, 25, 65

The list of prime factors of all numbers are

Prime factors of 86 are 2 x 43

Prime factors of 38 are 2 x 19

Prime factors of 25 are 5 x 5

Prime factors of 65 are 5 x 13

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

Given numbers are 86, 38, 25, 65

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

Apply this formula for all numbers.

Step1:

LCM(86, 38) = 1634

GCD(86, 38) = ( 86 x 38 ) / 1634

= 86 / 38

= 86

Step2:

LCM(2, 25) = 50

GCD(2, 25) = ( 2 x 25 ) / 50

= 2 / 25

= 2

Step3:

LCM(1, 65) = 65

GCD(1, 65) = ( 1 x 65 ) / 65

= 1 / 65

= 1

So, Greatest Common Divisor of 86, 38, 25, 65 is 1
