Given numbers are 760, 408, 665, 398

The list of prime factors of all numbers are

Prime factors of 760 are 2 x 2 x 2 x 5 x 19

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

Prime factors of 665 are 5 x 7 x 19

Prime factors of 398 are 2 x 199

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

Given numbers are 760, 408, 665, 398

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

Apply this formula for all numbers.

Step1:

LCM(760, 408) = 38760

GCD(760, 408) = ( 760 x 408 ) / 38760

= 760 / 408

= 760

Step2:

LCM(8, 665) = 5320

GCD(8, 665) = ( 8 x 665 ) / 5320

= 8 / 665

= 8

Step3:

LCM(1, 398) = 398

GCD(1, 398) = ( 1 x 398 ) / 398

= 1 / 398

= 1

So, Greatest Common Divisor of 760, 408, 665, 398 is 1
