Given numbers are 858, 308, 549, 840

The list of prime factors of all numbers are

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

Prime factors of 308 are 2 x 2 x 7 x 11

Prime factors of 549 are 3 x 3 x 61

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

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

Given numbers are 858, 308, 549, 840

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

Apply this formula for all numbers.

Step1:

LCM(858, 308) = 12012

GCD(858, 308) = ( 858 x 308 ) / 12012

= 858 / 308

= 858

Step2:

LCM(22, 549) = 12078

GCD(22, 549) = ( 22 x 549 ) / 12078

= 22 / 549

= 22

Step3:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

So, Greatest Common Divisor of 858, 308, 549, 840 is 1
