Given numbers are 247, 845, 785, 862

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

Apply this formula for all numbers.

Step1:

LCM(247, 845) = 16055

GCD(247, 845) = ( 247 x 845 ) / 16055

= 247 / 845

= 247

Step2:

LCM(13, 785) = 10205

GCD(13, 785) = ( 13 x 785 ) / 10205

= 13 / 785

= 13

Step3:

LCM(1, 862) = 862

GCD(1, 862) = ( 1 x 862 ) / 862

= 1 / 862

= 1

So, Greatest Common Divisor of 247, 845, 785, 862 is 1
