The smallest number that both 21 and 23 can go into is 483.
9 is composite.
3x + 15y = 33 4x - 3y = 66 3x + 15y = 33 divide by 3 to both sides x + 5y = 11 subtract 5y from both sides x = 11 - 5y 4x - 3y = 66, replace x with 11- 5y 4(11 - 5y) - 3y = 66 44 - 20y - 3y = 66 subtract 44 from both sides -23y = 22 divide by -23 to both sides y = -22/23 x = 11 - 5y replace y with -22/23 x = 11 - 5(-22/23) x = 11 + 110/23 x = (11*23 + 110)/23 x = 363/23
11 and 15 both go into 165. 165 is the LCM (Least Common Multiple) of 11 and 15.
As 11 is prime, only 1 will go into both.
The smallest number that both 21 and 23 can go into is 483.
11 and 23 are both prime numbers so they have no factors other than 1 and themselves.
9 is composite.
253 11 x 23 Both 11 and 23 are prime numbers, so the factor tree is complete.

3x + 15y = 33 4x - 3y = 66 3x + 15y = 33 divide by 3 to both sides x + 5y = 11 subtract 5y from both sides x = 11 - 5y 4x - 3y = 66, replace x with 11- 5y 4(11 - 5y) - 3y = 66 44 - 20y - 3y = 66 subtract 44 from both sides -23y = 22 divide by -23 to both sides y = -22/23 x = 11 - 5y replace y with -22/23 x = 11 - 5(-22/23) x = 11 + 110/23 x = (11*23 + 110)/23 x = 363/23
