Given numbers are 391, 778, 549, 479

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

Apply this formula for all numbers.

Step1:

LCM(391, 778) = 304198

GCD(391, 778) = ( 391 x 778 ) / 304198

= 391 / 778

= 391

Step2:

LCM(1, 549) = 549

GCD(1, 549) = ( 1 x 549 ) / 549

= 1 / 549

= 1

Step3:

LCM(1, 479) = 479

GCD(1, 479) = ( 1 x 479 ) / 479

= 1 / 479

= 1

So, Greatest Common Divisor of 391, 778, 549, 479 is 1
