Given numbers are 170, 292, 81, 840

The list of prime factors of all numbers are

Prime factors of 170 are 2 x 5 x 17

Prime factors of 292 are 2 x 2 x 73

Prime factors of 81 are 3 x 3 x 3 x 3

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 170, 292, 81, 840

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

Apply this formula for all numbers.

Step1:

LCM(170, 292) = 24820

GCD(170, 292) = ( 170 x 292 ) / 24820

= 170 / 292

= 170

Step2:

LCM(2, 81) = 162

GCD(2, 81) = ( 2 x 81 ) / 162

= 2 / 81

= 2

Step3:

LCM(1, 840) = 840

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

= 1 / 840

= 1

So, Greatest Common Divisor of 170, 292, 81, 840 is 1
