Given numbers are 500, 121, 640, 890

The list of prime factors of all numbers are

Prime factors of 500 are 2 x 2 x 5 x 5 x 5

Prime factors of 121 are 11 x 11

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 890 are 2 x 5 x 89

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

Given numbers are 500, 121, 640, 890

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

Apply this formula for all numbers.

Step1:

LCM(500, 121) = 60500

GCD(500, 121) = ( 500 x 121 ) / 60500

= 500 / 121

= 500

Step2:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

Step3:

LCM(1, 890) = 890

GCD(1, 890) = ( 1 x 890 ) / 890

= 1 / 890

= 1

So, Greatest Common Divisor of 500, 121, 640, 890 is 1
