Given numbers are 155, 764, 705, 858

The list of prime factors of all numbers are

Prime factors of 155 are 5 x 31

Prime factors of 764 are 2 x 2 x 191

Prime factors of 705 are 3 x 5 x 47

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 155, 764, 705, 858

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

Apply this formula for all numbers.

Step1:

LCM(155, 764) = 118420

GCD(155, 764) = ( 155 x 764 ) / 118420

= 155 / 764

= 155

Step2:

LCM(1, 705) = 705

GCD(1, 705) = ( 1 x 705 ) / 705

= 1 / 705

= 1

Step3:

LCM(1, 858) = 858

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

= 1 / 858

= 1

So, Greatest Common Divisor of 155, 764, 705, 858 is 1
