Given numbers are 22, 47, 65, 20

The list of prime factors of all numbers are

Prime factors of 22 are 2 x 11

Prime factors of 47 are 47

Prime factors of 65 are 5 x 13

Prime factors of 20 are 2 x 2 x 5

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

Given numbers are 22, 47, 65, 20

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

Apply this formula for all numbers.

Step1:

LCM(22, 47) = 1034

GCD(22, 47) = ( 22 x 47 ) / 1034

= 22 / 47

= 22

Step2:

LCM(1, 65) = 65

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

= 1 / 65

= 1

Step3:

LCM(1, 20) = 20

GCD(1, 20) = ( 1 x 20 ) / 20

= 1 / 20

= 1

So, Greatest Common Divisor of 22, 47, 65, 20 is 1
