Given numbers are 840, 245, 111, 298

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 245 are 5 x 7 x 7

Prime factors of 111 are 3 x 37

Prime factors of 298 are 2 x 149

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

Given numbers are 840, 245, 111, 298

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

Apply this formula for all numbers.

Step1:

LCM(840, 245) = 5880

GCD(840, 245) = ( 840 x 245 ) / 5880

= 840 / 245

= 840

Step2:

LCM(35, 111) = 3885

GCD(35, 111) = ( 35 x 111 ) / 3885

= 35 / 111

= 35

Step3:

LCM(1, 298) = 298

GCD(1, 298) = ( 1 x 298 ) / 298

= 1 / 298

= 1

So, Greatest Common Divisor of 840, 245, 111, 298 is 1
