Given numbers are 862, 660, 945, 858

The list of prime factors of all numbers are

Prime factors of 862 are 2 x 431

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

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 862, 660, 945, 858

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

Apply this formula for all numbers.

Step1:

LCM(862, 660) = 284460

GCD(862, 660) = ( 862 x 660 ) / 284460

= 862 / 660

= 862

Step2:

LCM(2, 945) = 1890

GCD(2, 945) = ( 2 x 945 ) / 1890

= 2 / 945

= 2

Step3:

LCM(1, 858) = 858

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

= 1 / 858

= 1

So, Greatest Common Divisor of 862, 660, 945, 858 is 1
