Given numbers are 855, 208, 813, 894

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

Apply this formula for all numbers.

Step1:

LCM(855, 208) = 177840

GCD(855, 208) = ( 855 x 208 ) / 177840

= 855 / 208

= 855

Step2:

LCM(1, 813) = 813

GCD(1, 813) = ( 1 x 813 ) / 813

= 1 / 813

= 1

Step3:

LCM(1, 894) = 894

GCD(1, 894) = ( 1 x 894 ) / 894

= 1 / 894

= 1

So, Greatest Common Divisor of 855, 208, 813, 894 is 1
