Given numbers are 153, 847, 434, 858

The list of prime factors of all numbers are

Prime factors of 153 are 3 x 3 x 17

Prime factors of 847 are 7 x 11 x 11

Prime factors of 434 are 2 x 7 x 31

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 153, 847, 434, 858

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

Apply this formula for all numbers.

Step1:

LCM(153, 847) = 129591

GCD(153, 847) = ( 153 x 847 ) / 129591

= 153 / 847

= 153

Step2:

LCM(1, 434) = 434

GCD(1, 434) = ( 1 x 434 ) / 434

= 1 / 434

= 1

Step3:

LCM(1, 858) = 858

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

= 1 / 858

= 1

So, Greatest Common Divisor of 153, 847, 434, 858 is 1
