Given numbers are 856, 436, 756, 278

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

Apply this formula for all numbers.

Step1:

LCM(856, 436) = 93304

GCD(856, 436) = ( 856 x 436 ) / 93304

= 856 / 436

= 856

Step2:

LCM(4, 756) = 756

GCD(4, 756) = ( 4 x 756 ) / 756

= 4 / 756

= 4

Step3:

LCM(4, 278) = 556

GCD(4, 278) = ( 4 x 278 ) / 556

= 4 / 278

= 4

So, Greatest Common Divisor of 856, 436, 756, 278 is 2
