Given numbers are 285, 786, 292, 721

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

Apply this formula for all numbers.

Step1:

LCM(285, 786) = 74670

GCD(285, 786) = ( 285 x 786 ) / 74670

= 285 / 786

= 285

Step2:

LCM(3, 292) = 876

GCD(3, 292) = ( 3 x 292 ) / 876

= 3 / 292

= 3

Step3:

LCM(1, 721) = 721

GCD(1, 721) = ( 1 x 721 ) / 721

= 1 / 721

= 1

So, Greatest Common Divisor of 285, 786, 292, 721 is 1
