Given numbers are 648, 492, 182, 145

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 492 are 2 x 2 x 3 x 41

Prime factors of 182 are 2 x 7 x 13

Prime factors of 145 are 5 x 29

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

Given numbers are 648, 492, 182, 145

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

Apply this formula for all numbers.

Step1:

LCM(648, 492) = 26568

GCD(648, 492) = ( 648 x 492 ) / 26568

= 648 / 492

= 648

Step2:

LCM(12, 182) = 1092

GCD(12, 182) = ( 12 x 182 ) / 1092

= 12 / 182

= 12

Step3:

LCM(2, 145) = 290

GCD(2, 145) = ( 2 x 145 ) / 290

= 2 / 145

= 2

So, Greatest Common Divisor of 648, 492, 182, 145 is 1
