Given numbers are 811, 865, 70

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

Apply this formula for all numbers.

Step1:

LCM(811, 865) = 701515

GCD(811, 865) = ( 811 x 865 ) / 701515

= 811 / 865

= 811

Step2:

LCM(1, 70) = 70

GCD(1, 70) = ( 1 x 70 ) / 70

= 1 / 70

= 1

So, Greatest Common Divisor of 811, 865, 70 is 1
