Given numbers are 858, 840, 247, 411

The list of prime factors of all numbers are

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

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

Prime factors of 247 are 13 x 19

Prime factors of 411 are 3 x 137

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

Given numbers are 858, 840, 247, 411

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

Apply this formula for all numbers.

Step1:

LCM(858, 840) = 120120

GCD(858, 840) = ( 858 x 840 ) / 120120

= 858 / 840

= 858

Step2:

LCM(6, 247) = 1482

GCD(6, 247) = ( 6 x 247 ) / 1482

= 6 / 247

= 6

Step3:

LCM(1, 411) = 411

GCD(1, 411) = ( 1 x 411 ) / 411

= 1 / 411

= 1

So, Greatest Common Divisor of 858, 840, 247, 411 is 1
