Given numbers are 840, 470, 998, 665

The list of prime factors of all numbers are

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

Prime factors of 470 are 2 x 5 x 47

Prime factors of 998 are 2 x 499

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 840, 470, 998, 665

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

Apply this formula for all numbers.

Step1:

LCM(840, 470) = 39480

GCD(840, 470) = ( 840 x 470 ) / 39480

= 840 / 470

= 840

Step2:

LCM(10, 998) = 4990

GCD(10, 998) = ( 10 x 998 ) / 4990

= 10 / 998

= 10

Step3:

LCM(2, 665) = 1330

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

= 2 / 665

= 2

So, Greatest Common Divisor of 840, 470, 998, 665 is 1
