Given numbers are 391, 705, 278, 335

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

Apply this formula for all numbers.

Step1:

LCM(391, 705) = 275655

GCD(391, 705) = ( 391 x 705 ) / 275655

= 391 / 705

= 391

Step2:

LCM(1, 278) = 278

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

= 1 / 278

= 1

Step3:

LCM(1, 335) = 335

GCD(1, 335) = ( 1 x 335 ) / 335

= 1 / 335

= 1

So, Greatest Common Divisor of 391, 705, 278, 335 is 1
