Given numbers are 548, 130, 778, 321

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

Apply this formula for all numbers.

Step1:

LCM(548, 130) = 35620

GCD(548, 130) = ( 548 x 130 ) / 35620

= 548 / 130

= 548

Step2:

LCM(2, 778) = 778

GCD(2, 778) = ( 2 x 778 ) / 778

= 2 / 778

= 2

Step3:

LCM(2, 321) = 642

GCD(2, 321) = ( 2 x 321 ) / 642

= 2 / 321

= 2

So, Greatest Common Divisor of 548, 130, 778, 321 is 1
