Given numbers are 782, 164, 815

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

Apply this formula for all numbers.

Step1:

LCM(782, 164) = 64124

GCD(782, 164) = ( 782 x 164 ) / 64124

= 782 / 164

= 782

Step2:

LCM(2, 815) = 1630

GCD(2, 815) = ( 2 x 815 ) / 1630

= 2 / 815

= 2

So, Greatest Common Divisor of 782, 164, 815 is 1
