Given numbers are 648, 285, 603, 358

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 285 are 3 x 5 x 19

Prime factors of 603 are 3 x 3 x 67

Prime factors of 358 are 2 x 179

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

Given numbers are 648, 285, 603, 358

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

Apply this formula for all numbers.

Step1:

LCM(648, 285) = 61560

GCD(648, 285) = ( 648 x 285 ) / 61560

= 648 / 285

= 648

Step2:

LCM(3, 603) = 603

GCD(3, 603) = ( 3 x 603 ) / 603

= 3 / 603

= 3

Step3:

LCM(3, 358) = 1074

GCD(3, 358) = ( 3 x 358 ) / 1074

= 3 / 358

= 3

So, Greatest Common Divisor of 648, 285, 603, 358 is 1
