Given numbers are 905, 355, 491, 278

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

Apply this formula for all numbers.

Step1:

LCM(905, 355) = 64255

GCD(905, 355) = ( 905 x 355 ) / 64255

= 905 / 355

= 905

Step2:

LCM(5, 491) = 2455

GCD(5, 491) = ( 5 x 491 ) / 2455

= 5 / 491

= 5

Step3:

LCM(1, 278) = 278

GCD(1, 278) = ( 1 x 278 ) / 278

= 1 / 278

= 1

So, Greatest Common Divisor of 905, 355, 491, 278 is 1
