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.
1, 3, 7, 9, 21, 63.
21 and 9 21 - 9 = 12 21+9 = 30
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.
