Oh, dude, 9 and 21 both go into numbers that are multiples of both 9 and 21. So, like, they can go into numbers like 63, 126, 189, and so on. It's just basic math, nothing too mind-blowing.
1, 3, 7, 9, 21 and 63.
21 and 9 21 - 9 = 12 21+9 = 30
1, 3, 7, 9, 21, 27, 63, 189.
1, 3, 7, 9, 21, 27, 63, 189.
To determine how many times 21 can go into 189, you would perform the division 189 ÷ 21. The quotient is 9, meaning that 21 can go into 189 nine times without any remainder. This can also be expressed as 189 = 21 x 9.
1 and 3.
1, 3, 7, 9, 21 and 63.
1, 3, 7, 9, 21, 63.
1, 3, 7, 9, 21, 63.
1, 3, 7, 9, 21, 63.
21 and 9 21 - 9 = 12 21+9 = 30
1, 3, 7, 9, 21, 63.
The GCF of 9 and 21 is 3.
1, 3, 7, 9, 21, 27, 63, 189.
1, 3, 7, 9, 21, 27, 63, 189.
These are the whole numbers that go into 126 evenly: 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126.
The number 63 can be evenly divided by 1, 3, 7, 9, 21, and 63.
