Given numbers are 980, 638, 809, 201

The list of prime factors of all numbers are

Prime factors of 980 are 2 x 2 x 5 x 7 x 7

Prime factors of 638 are 2 x 11 x 29

Prime factors of 809 are 809

Prime factors of 201 are 3 x 67

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

Given numbers are 980, 638, 809, 201

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

Apply this formula for all numbers.

Step1:

LCM(980, 638) = 312620

GCD(980, 638) = ( 980 x 638 ) / 312620

= 980 / 638

= 980

Step2:

LCM(2, 809) = 1618

GCD(2, 809) = ( 2 x 809 ) / 1618

= 2 / 809

= 2

Step3:

LCM(1, 201) = 201

GCD(1, 201) = ( 1 x 201 ) / 201

= 1 / 201

= 1

So, Greatest Common Divisor of 980, 638, 809, 201 is 1
