Given numbers are 285, 492, 835, 781

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

Apply this formula for all numbers.

Step1:

LCM(285, 492) = 46740

GCD(285, 492) = ( 285 x 492 ) / 46740

= 285 / 492

= 285

Step2:

LCM(3, 835) = 2505

GCD(3, 835) = ( 3 x 835 ) / 2505

= 3 / 835

= 3

Step3:

LCM(1, 781) = 781

GCD(1, 781) = ( 1 x 781 ) / 781

= 1 / 781

= 1

So, Greatest Common Divisor of 285, 492, 835, 781 is 1
