Given numbers are 397, 148, 280

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

Apply this formula for all numbers.

Step1:

LCM(397, 148) = 58756

GCD(397, 148) = ( 397 x 148 ) / 58756

= 397 / 148

= 397

Step2:

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

= 1 / 280

= 1

So, Greatest Common Divisor of 397, 148, 280 is 1
