Given numbers are 648, 224, 755, 169

The list of prime factors of all numbers are

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

Prime factors of 224 are 2 x 2 x 2 x 2 x 2 x 7

Prime factors of 755 are 5 x 151

Prime factors of 169 are 13 x 13

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

Given numbers are 648, 224, 755, 169

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

Apply this formula for all numbers.

Step1:

LCM(648, 224) = 18144

GCD(648, 224) = ( 648 x 224 ) / 18144

= 648 / 224

= 648

Step2:

LCM(8, 755) = 6040

GCD(8, 755) = ( 8 x 755 ) / 6040

= 8 / 755

= 8

Step3:

LCM(1, 169) = 169

GCD(1, 169) = ( 1 x 169 ) / 169

= 1 / 169

= 1

So, Greatest Common Divisor of 648, 224, 755, 169 is 1
