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

Apply this formula for all numbers.

Step1:

LCM(105, 295) = 6195

GCD(105, 295) = ( 105 x 295 ) / 6195

= 105 / 295

= 105

Step2:

LCM(5, 840) = 840

GCD(5, 840) = ( 5 x 840 ) / 840

= 5 / 840

= 5

So, Greatest Common Divisor of 105, 295, 840 is 5
