Given numbers are 478, 714, 280, 221

The list of prime factors of all numbers are

Prime factors of 478 are 2 x 239

Prime factors of 714 are 2 x 3 x 7 x 17

Prime factors of 280 are 2 x 2 x 2 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 478, 714, 280, 221

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

Apply this formula for all numbers.

Step1:

LCM(478, 714) = 170646

GCD(478, 714) = ( 478 x 714 ) / 170646

= 478 / 714

= 478

Step2:

LCM(2, 280) = 280

GCD(2, 280) = ( 2 x 280 ) / 280

= 2 / 280

= 2

Step3:

LCM(2, 221) = 442

GCD(2, 221) = ( 2 x 221 ) / 442

= 2 / 221

= 2

So, Greatest Common Divisor of 478, 714, 280, 221 is 1
