Given numbers are 842, 287, 906, 681

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

Apply this formula for all numbers.

Step1:

LCM(842, 287) = 241654

GCD(842, 287) = ( 842 x 287 ) / 241654

= 842 / 287

= 842

Step2:

LCM(1, 906) = 906

GCD(1, 906) = ( 1 x 906 ) / 906

= 1 / 906

= 1

Step3:

LCM(1, 681) = 681

GCD(1, 681) = ( 1 x 681 ) / 681

= 1 / 681

= 1

So, Greatest Common Divisor of 842, 287, 906, 681 is 1
