Given numbers are 220, 242, 646, 841

The list of prime factors of all numbers are

Prime factors of 220 are 2 x 2 x 5 x 11

Prime factors of 242 are 2 x 11 x 11

Prime factors of 646 are 2 x 17 x 19

Prime factors of 841 are 29 x 29

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

Given numbers are 220, 242, 646, 841

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

Apply this formula for all numbers.

Step1:

LCM(220, 242) = 2420

GCD(220, 242) = ( 220 x 242 ) / 2420

= 220 / 242

= 220

Step2:

LCM(22, 646) = 7106

GCD(22, 646) = ( 22 x 646 ) / 7106

= 22 / 646

= 22

Step3:

LCM(2, 841) = 1682

GCD(2, 841) = ( 2 x 841 ) / 1682

= 2 / 841

= 2

So, Greatest Common Divisor of 220, 242, 646, 841 is 1
