Given numbers are 298, 856, 783, 115

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

Apply this formula for all numbers.

Step1:

LCM(298, 856) = 127544

GCD(298, 856) = ( 298 x 856 ) / 127544

= 298 / 856

= 298

Step2:

LCM(2, 783) = 1566

GCD(2, 783) = ( 2 x 783 ) / 1566

= 2 / 783

= 2

Step3:

LCM(1, 115) = 115

GCD(1, 115) = ( 1 x 115 ) / 115

= 1 / 115

= 1

So, Greatest Common Divisor of 298, 856, 783, 115 is 1
