Given numbers are 831, 221, 514, 644

The list of prime factors of all numbers are

Prime factors of 831 are 3 x 277

Prime factors of 221 are 13 x 17

Prime factors of 514 are 2 x 257

Prime factors of 644 are 2 x 2 x 7 x 23

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

Given numbers are 831, 221, 514, 644

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

Apply this formula for all numbers.

Step1:

LCM(831, 221) = 183651

GCD(831, 221) = ( 831 x 221 ) / 183651

= 831 / 221

= 831

Step2:

LCM(1, 514) = 514

GCD(1, 514) = ( 1 x 514 ) / 514

= 1 / 514

= 1

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 831, 221, 514, 644 is 1
