Given numbers are 840, 989, 92, 855

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 989 are 23 x 43

Prime factors of 92 are 2 x 2 x 23

Prime factors of 855 are 3 x 3 x 5 x 19

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

Given numbers are 840, 989, 92, 855

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

Apply this formula for all numbers.

Step1:

LCM(840, 989) = 830760

GCD(840, 989) = ( 840 x 989 ) / 830760

= 840 / 989

= 840

Step2:

LCM(1, 92) = 92

GCD(1, 92) = ( 1 x 92 ) / 92

= 1 / 92

= 1

Step3:

LCM(1, 855) = 855

GCD(1, 855) = ( 1 x 855 ) / 855

= 1 / 855

= 1

So, Greatest Common Divisor of 840, 989, 92, 855 is 1
