Given numbers are 861, 350, 771, 221

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 350 are 2 x 5 x 5 x 7

Prime factors of 771 are 3 x 257

Prime factors of 221 are 13 x 17

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

Given numbers are 861, 350, 771, 221

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

Apply this formula for all numbers.

Step1:

LCM(861, 350) = 43050

GCD(861, 350) = ( 861 x 350 ) / 43050

= 861 / 350

= 861

Step2:

LCM(7, 771) = 5397

GCD(7, 771) = ( 7 x 771 ) / 5397

= 7 / 771

= 7

Step3:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1

So, Greatest Common Divisor of 861, 350, 771, 221 is 1
