Given numbers are 874, 390, 744, 655

The list of prime factors of all numbers are

Prime factors of 874 are 2 x 19 x 23

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 744 are 2 x 2 x 2 x 3 x 31

Prime factors of 655 are 5 x 131

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

Given numbers are 874, 390, 744, 655

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

Apply this formula for all numbers.

Step1:

LCM(874, 390) = 170430

GCD(874, 390) = ( 874 x 390 ) / 170430

= 874 / 390

= 874

Step2:

LCM(2, 744) = 744

GCD(2, 744) = ( 2 x 744 ) / 744

= 2 / 744

= 2

Step3:

LCM(2, 655) = 1310

GCD(2, 655) = ( 2 x 655 ) / 1310

= 2 / 655

= 2

So, Greatest Common Divisor of 874, 390, 744, 655 is 1
