Given numbers are 343, 172, 290

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

Apply this formula for all numbers.

Step1:

LCM(343, 172) = 58996

GCD(343, 172) = ( 343 x 172 ) / 58996

= 343 / 172

= 343

Step2:

LCM(1, 290) = 290

GCD(1, 290) = ( 1 x 290 ) / 290

= 1 / 290

= 1

So, Greatest Common Divisor of 343, 172, 290 is 1
