Given numbers are 397, 620, 746

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

Apply this formula for all numbers.

Step1:

LCM(397, 620) = 246140

GCD(397, 620) = ( 397 x 620 ) / 246140

= 397 / 620

= 397

Step2:

LCM(1, 746) = 746

GCD(1, 746) = ( 1 x 746 ) / 746

= 1 / 746

= 1

So, Greatest Common Divisor of 397, 620, 746 is 1
