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.
93 รท 15 = 6 with remainder 3
15: 15 one 6: 2, 3, 6 three
6 with remainder 3.
The HCF is 3
15 times. (6 times 15 =90)
-15
15 + 3 - 6 / 2 * 6 = 15 + 3 - 3 * 6 = 15 + 3 - 18 = 18 - 18 = 0
[(15 + 6) ÷ 3] + 10 (6 - 3) =
3 times, 5x3=15 so its 3 times
The common factors of 6 and 15 is 1 and 3 that's all
The GCF of 3, 6, and 15 is 3.
