Given numbers are 678, 291, 815, 584

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

Apply this formula for all numbers.

Step1:

LCM(678, 291) = 65766

GCD(678, 291) = ( 678 x 291 ) / 65766

= 678 / 291

= 678

Step2:

LCM(3, 815) = 2445

GCD(3, 815) = ( 3 x 815 ) / 2445

= 3 / 815

= 3

Step3:

LCM(1, 584) = 584

GCD(1, 584) = ( 1 x 584 ) / 584

= 1 / 584

= 1

So, Greatest Common Divisor of 678, 291, 815, 584 is 1
