Given numbers are 220, 268, 642, 489

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

Apply this formula for all numbers.

Step1:

LCM(220, 268) = 14740

GCD(220, 268) = ( 220 x 268 ) / 14740

= 220 / 268

= 220

Step2:

LCM(4, 642) = 1284

GCD(4, 642) = ( 4 x 642 ) / 1284

= 4 / 642

= 4

Step3:

LCM(2, 489) = 978

GCD(2, 489) = ( 2 x 489 ) / 978

= 2 / 489

= 2

So, Greatest Common Divisor of 220, 268, 642, 489 is 1
