Given numbers are 247, 128, 835

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

Apply this formula for all numbers.

Step1:

LCM(247, 128) = 31616

GCD(247, 128) = ( 247 x 128 ) / 31616

= 247 / 128

= 247

Step2:

LCM(1, 835) = 835

GCD(1, 835) = ( 1 x 835 ) / 835

= 1 / 835

= 1

So, Greatest Common Divisor of 247, 128, 835 is 1
