Given numbers are 856, 844, 561, 981

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

Apply this formula for all numbers.

Step1:

LCM(856, 844) = 180616

GCD(856, 844) = ( 856 x 844 ) / 180616

= 856 / 844

= 856

Step2:

LCM(4, 561) = 2244

GCD(4, 561) = ( 4 x 561 ) / 2244

= 4 / 561

= 4

Step3:

LCM(1, 981) = 981

GCD(1, 981) = ( 1 x 981 ) / 981

= 1 / 981

= 1

So, Greatest Common Divisor of 856, 844, 561, 981 is 1
