Given numbers are 805, 276, 78

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

Apply this formula for all numbers.

Step1:

LCM(805, 276) = 9660

GCD(805, 276) = ( 805 x 276 ) / 9660

= 805 / 276

= 805

Step2:

LCM(23, 78) = 1794

GCD(23, 78) = ( 23 x 78 ) / 1794

= 23 / 78

= 23

So, Greatest Common Divisor of 805, 276, 78 is 1
