No, because 6 times 2 is 12 and so 6 can't go into 15 evenly
They have a common factor of 3.1, 2, 3, and 6 go into 6.1, 3, 5, and 15 go into 15.1 and 3 both go into 6 and 15.
15 can go into 6 times 0 times with a remainder of 6. (6 / 15 = 0.4)
15: 15 one 6: 2, 3, 6 three
15 ÷ 6 times
90 divided by 15 = 6
6
6 times, remainder 15
108 ÷ 15 = 7.2
The lowest number that both 6 and 15 can go into is 30.
6 goes into 90 15 times
93 รท 15 = 6 with remainder 3
15 times. (6 times 15 =90)
