Given numbers are 840, 287, 55, 848

The list of prime factors of all numbers are

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

Prime factors of 287 are 7 x 41

Prime factors of 55 are 5 x 11

Prime factors of 848 are 2 x 2 x 2 x 2 x 53

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

Given numbers are 840, 287, 55, 848

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

Apply this formula for all numbers.

Step1:

LCM(840, 287) = 34440

GCD(840, 287) = ( 840 x 287 ) / 34440

= 840 / 287

= 840

Step2:

LCM(7, 55) = 385

GCD(7, 55) = ( 7 x 55 ) / 385

= 7 / 55

= 7

Step3:

LCM(1, 848) = 848

GCD(1, 848) = ( 1 x 848 ) / 848

= 1 / 848

= 1

So, Greatest Common Divisor of 840, 287, 55, 848 is 1
