Given numbers are 345, 287, 793, 215

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

Apply this formula for all numbers.

Step1:

LCM(345, 287) = 99015

GCD(345, 287) = ( 345 x 287 ) / 99015

= 345 / 287

= 345

Step2:

LCM(1, 793) = 793

GCD(1, 793) = ( 1 x 793 ) / 793

= 1 / 793

= 1

Step3:

LCM(1, 215) = 215

GCD(1, 215) = ( 1 x 215 ) / 215

= 1 / 215

= 1

So, Greatest Common Divisor of 345, 287, 793, 215 is 1
