Given numbers are 486, 378, 909, 220

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

Apply this formula for all numbers.

Step1:

LCM(486, 378) = 3402

GCD(486, 378) = ( 486 x 378 ) / 3402

= 486 / 378

= 486

Step2:

LCM(54, 909) = 5454

GCD(54, 909) = ( 54 x 909 ) / 5454

= 54 / 909

= 54

Step3:

LCM(9, 220) = 1980

GCD(9, 220) = ( 9 x 220 ) / 1980

= 9 / 220

= 9

So, Greatest Common Divisor of 486, 378, 909, 220 is 1
