Given numbers are 471, 987, 945, 221

The list of prime factors of all numbers are

Prime factors of 471 are 3 x 157

Prime factors of 987 are 3 x 7 x 47

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

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 471, 987, 945, 221

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

Apply this formula for all numbers.

Step1:

LCM(471, 987) = 154959

GCD(471, 987) = ( 471 x 987 ) / 154959

= 471 / 987

= 471

Step2:

LCM(3, 945) = 945

GCD(3, 945) = ( 3 x 945 ) / 945

= 3 / 945

= 3

Step3:

LCM(3, 221) = 663

GCD(3, 221) = ( 3 x 221 ) / 663

= 3 / 221

= 3

So, Greatest Common Divisor of 471, 987, 945, 221 is 1
