Given numbers are 538, 608, 945, 648

The list of prime factors of all numbers are

Prime factors of 538 are 2 x 269

Prime factors of 608 are 2 x 2 x 2 x 2 x 2 x 19

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

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 538, 608, 945, 648

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

Apply this formula for all numbers.

Step1:

LCM(538, 608) = 163552

GCD(538, 608) = ( 538 x 608 ) / 163552

= 538 / 608

= 538

Step2:

LCM(2, 945) = 1890

GCD(2, 945) = ( 2 x 945 ) / 1890

= 2 / 945

= 2

Step3:

LCM(1, 648) = 648

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

= 1 / 648

= 1

So, Greatest Common Divisor of 538, 608, 945, 648 is 1
