Given numbers are 486, 978, 248, 312

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

Apply this formula for all numbers.

Step1:

LCM(486, 978) = 79218

GCD(486, 978) = ( 486 x 978 ) / 79218

= 486 / 978

= 486

Step2:

LCM(6, 248) = 744

GCD(6, 248) = ( 6 x 248 ) / 744

= 6 / 248

= 6

Step3:

LCM(2, 312) = 312

GCD(2, 312) = ( 2 x 312 ) / 312

= 2 / 312

= 2

So, Greatest Common Divisor of 486, 978, 248, 312 is 2
