The hcf of 15 and 20 is 5
15 and 5 both go into every multiple of 15 .
They both go into 90.
11 and 15 both go into 165. 165 is the LCM (Least Common Multiple) of 11 and 15.
three quarters 15/20 divide both by 5 = 3/4
15 and 20 would both go into 60. Or 300. And several others.
They both go into multiples of 60 such as 480.
15/20 = 3/4 Divide both 15 and 20 by 5.
The hcf of 15 and 20 is 5
15 and 5 both go into every multiple of 15 .
It is 20. 300/15=20.
10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, +5 . . .
300 ÷ 20 = 15
They both go into 90.
The first number they both go into is 60. (Lowest Common Multiple = 60 = 12 X 5 & 15 X 4).
15/20 in simplest form is 3/4. Both 15 and 20 can be divided by 5 to simplify the fraction.
312÷15 = 20 remainder 12
