Given numbers are 455, 721, 176

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

Apply this formula for all numbers.

Step1:

LCM(455, 721) = 46865

GCD(455, 721) = ( 455 x 721 ) / 46865

= 455 / 721

= 455

Step2:

LCM(7, 176) = 1232

GCD(7, 176) = ( 7 x 176 ) / 1232

= 7 / 176

= 7

So, Greatest Common Divisor of 455, 721, 176 is 1
