Given numbers are 217, 820, 254, 187

The list of prime factors of all numbers are

Prime factors of 217 are 7 x 31

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 254 are 2 x 127

Prime factors of 187 are 11 x 17

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

Given numbers are 217, 820, 254, 187

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

Apply this formula for all numbers.

Step1:

LCM(217, 820) = 177940

GCD(217, 820) = ( 217 x 820 ) / 177940

= 217 / 820

= 217

Step2:

LCM(1, 254) = 254

GCD(1, 254) = ( 1 x 254 ) / 254

= 1 / 254

= 1

Step3:

LCM(1, 187) = 187

GCD(1, 187) = ( 1 x 187 ) / 187

= 1 / 187

= 1

So, Greatest Common Divisor of 217, 820, 254, 187 is 1
