Given numbers are 312, 609, 79, 278

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

Apply this formula for all numbers.

Step1:

LCM(312, 609) = 63336

GCD(312, 609) = ( 312 x 609 ) / 63336

= 312 / 609

= 312

Step2:

LCM(3, 79) = 237

GCD(3, 79) = ( 3 x 79 ) / 237

= 3 / 79

= 3

Step3:

LCM(1, 278) = 278

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

= 1 / 278

= 1

So, Greatest Common Divisor of 312, 609, 79, 278 is 1
