Given numbers are 742, 840, 960, 665

The list of prime factors of all numbers are

Prime factors of 742 are 2 x 7 x 53

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 960 are 2 x 2 x 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 665 are 5 x 7 x 19

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

Given numbers are 742, 840, 960, 665

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

Apply this formula for all numbers.

Step1:

LCM(742, 840) = 44520

GCD(742, 840) = ( 742 x 840 ) / 44520

= 742 / 840

= 742

Step2:

LCM(14, 960) = 6720

GCD(14, 960) = ( 14 x 960 ) / 6720

= 14 / 960

= 14

Step3:

LCM(2, 665) = 1330

GCD(2, 665) = ( 2 x 665 ) / 1330

= 2 / 665

= 2

So, Greatest Common Divisor of 742, 840, 960, 665 is 1
