1, 67

Divisors of 21 :

The positive integer divisors of 21 that completely divides 21 are.

1, 3, 7, 21

Divisors of 20 :

The positive integer divisors of 20 that completely divides 20 are.

1, 2, 4, 5, 10, 20

GCD of numbers is the greatest common divisor

So, the GCD (50, 67, 21, 20) = 1.

Given numbers are 50, 67, 21, 20

The list of prime factors of all numbers are

Prime factors of 50 are 2 x 5 x 5

Prime factors of 67 are 67

Prime factors of 21 are 3 x 7

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 50, 67, 21, 20

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

Apply this formula for all numbers.

Step1:

LCM(50, 67) = 3350

GCD(50, 67) = ( 50 x 67 ) / 3350

= 50 / 67

= 50

Step2:

LCM(1, 21) = 21

GCD(1, 21) = ( 1 x 21 ) / 21

= 1 / 21

= 1

Step3:

LCM(1, 20) = 20

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

= 1 / 20

= 1

So, Greatest Common Divisor of 50, 67, 21, 20 is 1
