Given numbers are 783, 858, 868, 653

The list of prime factors of all numbers are

Prime factors of 783 are 3 x 3 x 3 x 29

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

Prime factors of 868 are 2 x 2 x 7 x 31

Prime factors of 653 are 653

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

Given numbers are 783, 858, 868, 653

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

Apply this formula for all numbers.

Step1:

LCM(783, 858) = 223938

GCD(783, 858) = ( 783 x 858 ) / 223938

= 783 / 858

= 783

Step2:

LCM(3, 868) = 2604

GCD(3, 868) = ( 3 x 868 ) / 2604

= 3 / 868

= 3

Step3:

LCM(1, 653) = 653

GCD(1, 653) = ( 1 x 653 ) / 653

= 1 / 653

= 1

So, Greatest Common Divisor of 783, 858, 868, 653 is 1
