Composite Numbers

693 can be divided by 3 ==> composite number.

This is an easy prime because if you make a sum of all the digits: 6 + 9 + 3 = 18, if you can devide this sum by 3 than you can also divide the original number by 3.

4 6 8 9 10 12 14 15 16 18 20 21 22 24 25 26 27 28 30 32 33 34 35 36 38 39 40 42 44 45 46 48 49 50 51 52 54 55 56 57 58 60 62 63 64 65 66 68 69 70 72 74 75 76 77 78 80 81 82 84 85 86 87 88 90 91 92 93 94 95 96 98 99 100 102 104 105 106 108 110 111 112 114 115 116 117 118 119 120 121 122 123 124 125 126 128 129 130 132 133 134 135 136 138 140 141 142 143 144 145 146 147 148 150 152 153 154 155 156 158 159 160 161 162 164 165 166 168 169 170 171 172 174 175 176 177 178 180 182 183 184 185 186 187 188 189 190 192 194 195 196 198 200 201 202 203 204 205 206 207 208 209 210 212 213 214 215 216 217 218 219 220 221 222 224 225 226 228 230 231 232 234 235 236 237 238 240 242 243 244 245 246 247 248 249 250 252 253 254 256 258 259 260 261 262 264 265 266 267 268 270 272 273 274 275 276 278 279 280 282 284 285 286 287 288 289 290 291 292 294 295 296 297 298 299 300

12, 49, and 99 are composite, the rest are prime.

When referring to positive integers, prime means having only two factors and composite means having more than two.

39 = 3 x 13

2 17 31 are prime

4, 6, 8, 9, 10, 12, 14, 15, 16, 18 are the first ten.

461 is prime.

Yes. You can very easily see that 6,237 is divisible by 9, since its digits add up to a multiple of 9.

60

25 is both square and composite

703 is a composite number because its factors are:

1x703

19x37

1, 19, 37 and 703

(If I'm incorrect, please excuse me! >:( )

the answer is 175.

composite, obviously

Because is is divisible - by 3, for example.

Hm

yes

They are all the numbers that are divisible by 2 with no remainder except 2 itself because it is the only even prime number.

It is composite.

All even numbers (except zero and two) are composite.

A composite number is a number that has additional factors besides ' 1 ' and itself.

The number ' 1 ' has no additional factors besides ' 1 ' and itself. So it's not a composite number.

Yes

89 is a prime number

Yes, it is a composite number because it is divisible by 3 which means it has more than two factors.

A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite.

prime: numbers that can only divided by 1 and itself (except 1)

composite: numbers had others factors except 1 and itself

1 - neither prime or composite
