Given numbers are 655, 290, 398, 326

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

Apply this formula for all numbers.

Step1:

LCM(655, 290) = 37990

GCD(655, 290) = ( 655 x 290 ) / 37990

= 655 / 290

= 655

Step2:

LCM(5, 398) = 1990

GCD(5, 398) = ( 5 x 398 ) / 1990

= 5 / 398

= 5

Step3:

LCM(1, 326) = 326

GCD(1, 326) = ( 1 x 326 ) / 326

= 1 / 326

= 1

So, Greatest Common Divisor of 655, 290, 398, 326 is 1
