Given numbers are 869, 815, 961, 284

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

Apply this formula for all numbers.

Step1:

LCM(869, 815) = 708235

GCD(869, 815) = ( 869 x 815 ) / 708235

= 869 / 815

= 869

Step2:

LCM(1, 961) = 961

GCD(1, 961) = ( 1 x 961 ) / 961

= 1 / 961

= 1

Step3:

LCM(1, 284) = 284

GCD(1, 284) = ( 1 x 284 ) / 284

= 1 / 284

= 1

So, Greatest Common Divisor of 869, 815, 961, 284 is 1
