Given numbers are 648, 438, 453, 758

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 438 are 2 x 3 x 73

Prime factors of 453 are 3 x 151

Prime factors of 758 are 2 x 379

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

Given numbers are 648, 438, 453, 758

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

Apply this formula for all numbers.

Step1:

LCM(648, 438) = 47304

GCD(648, 438) = ( 648 x 438 ) / 47304

= 648 / 438

= 648

Step2:

LCM(6, 453) = 906

GCD(6, 453) = ( 6 x 453 ) / 906

= 6 / 453

= 6

Step3:

LCM(3, 758) = 2274

GCD(3, 758) = ( 3 x 758 ) / 2274

= 3 / 758

= 3

So, Greatest Common Divisor of 648, 438, 453, 758 is 1
