Given numbers are 390, 940, 98, 549

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

Apply this formula for all numbers.

Step1:

LCM(390, 940) = 36660

GCD(390, 940) = ( 390 x 940 ) / 36660

= 390 / 940

= 390

Step2:

LCM(10, 98) = 490

GCD(10, 98) = ( 10 x 98 ) / 490

= 10 / 98

= 10

Step3:

LCM(2, 549) = 1098

GCD(2, 549) = ( 2 x 549 ) / 1098

= 2 / 549

= 2

So, Greatest Common Divisor of 390, 940, 98, 549 is 1
