Given numbers are 486, 969, 393, 815

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

Apply this formula for all numbers.

Step1:

LCM(486, 969) = 156978

GCD(486, 969) = ( 486 x 969 ) / 156978

= 486 / 969

= 486

Step2:

LCM(3, 393) = 393

GCD(3, 393) = ( 3 x 393 ) / 393

= 3 / 393

= 3

Step3:

LCM(3, 815) = 2445

GCD(3, 815) = ( 3 x 815 ) / 2445

= 3 / 815

= 3

So, Greatest Common Divisor of 486, 969, 393, 815 is 1
