Given numbers are 278, 678, 905, 241

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

Apply this formula for all numbers.

Step1:

LCM(278, 678) = 94242

GCD(278, 678) = ( 278 x 678 ) / 94242

= 278 / 678

= 278

Step2:

LCM(2, 905) = 1810

GCD(2, 905) = ( 2 x 905 ) / 1810

= 2 / 905

= 2

Step3:

LCM(1, 241) = 241

GCD(1, 241) = ( 1 x 241 ) / 241

= 1 / 241

= 1

So, Greatest Common Divisor of 278, 678, 905, 241 is 1
