Given numbers are 442, 169, 215, 648

The list of prime factors of all numbers are

Prime factors of 442 are 2 x 13 x 17

Prime factors of 169 are 13 x 13

Prime factors of 215 are 5 x 43

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

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

Given numbers are 442, 169, 215, 648

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

Apply this formula for all numbers.

Step1:

LCM(442, 169) = 5746

GCD(442, 169) = ( 442 x 169 ) / 5746

= 442 / 169

= 442

Step2:

LCM(13, 215) = 2795

GCD(13, 215) = ( 13 x 215 ) / 2795

= 13 / 215

= 13

Step3:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

So, Greatest Common Divisor of 442, 169, 215, 648 is 1
