Given numbers are 882, 670, 781, 221

The list of prime factors of all numbers are

Prime factors of 882 are 2 x 3 x 3 x 7 x 7

Prime factors of 670 are 2 x 5 x 67

Prime factors of 781 are 11 x 71

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 882, 670, 781, 221

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

Apply this formula for all numbers.

Step1:

LCM(882, 670) = 295470

GCD(882, 670) = ( 882 x 670 ) / 295470

= 882 / 670

= 882

Step2:

LCM(2, 781) = 1562

GCD(2, 781) = ( 2 x 781 ) / 1562

= 2 / 781

= 2

Step3:

LCM(1, 221) = 221

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

= 1 / 221

= 1

So, Greatest Common Divisor of 882, 670, 781, 221 is 1
