Given numbers are 287, 406, 487, 379

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

Apply this formula for all numbers.

Step1:

LCM(287, 406) = 16646

GCD(287, 406) = ( 287 x 406 ) / 16646

= 287 / 406

= 287

Step2:

LCM(7, 487) = 3409

GCD(7, 487) = ( 7 x 487 ) / 3409

= 7 / 487

= 7

Step3:

LCM(1, 379) = 379

GCD(1, 379) = ( 1 x 379 ) / 379

= 1 / 379

= 1

So, Greatest Common Divisor of 287, 406, 487, 379 is 1
