Given numbers are 325, 728, 946, 391

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

Apply this formula for all numbers.

Step1:

LCM(325, 728) = 18200

GCD(325, 728) = ( 325 x 728 ) / 18200

= 325 / 728

= 325

Step2:

LCM(13, 946) = 12298

GCD(13, 946) = ( 13 x 946 ) / 12298

= 13 / 946

= 13

Step3:

LCM(1, 391) = 391

GCD(1, 391) = ( 1 x 391 ) / 391

= 1 / 391

= 1

So, Greatest Common Divisor of 325, 728, 946, 391 is 1
