Given numbers are 665, 873, 661, 858

The list of prime factors of all numbers are

Prime factors of 665 are 5 x 7 x 19

Prime factors of 873 are 3 x 3 x 97

Prime factors of 661 are 661

Prime factors of 858 are 2 x 3 x 11 x 13

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

Given numbers are 665, 873, 661, 858

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

Apply this formula for all numbers.

Step1:

LCM(665, 873) = 580545

GCD(665, 873) = ( 665 x 873 ) / 580545

= 665 / 873

= 665

Step2:

LCM(1, 661) = 661

GCD(1, 661) = ( 1 x 661 ) / 661

= 1 / 661

= 1

Step3:

LCM(1, 858) = 858

GCD(1, 858) = ( 1 x 858 ) / 858

= 1 / 858

= 1

So, Greatest Common Divisor of 665, 873, 661, 858 is 1
