Given numbers are 325, 670, 13, 209

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

Apply this formula for all numbers.

Step1:

LCM(325, 670) = 43550

GCD(325, 670) = ( 325 x 670 ) / 43550

= 325 / 670

= 325

Step2:

LCM(5, 13) = 65

GCD(5, 13) = ( 5 x 13 ) / 65

= 5 / 13

= 5

Step3:

LCM(1, 209) = 209

GCD(1, 209) = ( 1 x 209 ) / 209

= 1 / 209

= 1

So, Greatest Common Divisor of 325, 670, 13, 209 is 1
