The numbers 2, 13, and 43 are prime. 143 is a composite number. Its positive integer factors, other than one and itself, are 11 and 13.
The GCF of 143, 195, and 260 is 13 The prime factorization of 143 is 11*13. The prime factorization of 195 is 13*15. The prime factorization of 260 is 2*2*5*13 So the GCF is 13.
43 is not evenly divisible by any prime lower than itself - so it is prime43 ÷ 2 = 21 + 143 ÷ 3 = 14 + 143 ÷ 5 = 8 + 343 ÷ 7 = 6 + 143 ÷ 11 = 3 + 1043 ÷ 13 = 3 + 443 ÷ 17 = 2 + 943 ÷ 19 = 2 + 543 ÷ 23 = 1 + 2043 ÷ 29 = 1 + 1443 ÷ 31 = 1 + 1243 ÷ 37 = 1 + 643 ÷ 41 = 1 + 243 is a Prime Number.It is prime.Prime Number
They are 11 times 13 = 143
143 = 11 x 13 The larger of the 2 primes is 13.
The prime factors are: 39 = 3 * 13 143 = 11 * 13 156 = 2 * 2 * 3 * 13 So the greatest common factor is 13.
143 is not prime - we can see this because it is 1 less than a square. x^2-1 = (x+1)(x-1), and for 143, x=12. Thus, 143=11*13.
11 x 13 = 143 3 x 5 x 13 = 195 2 x 2 x 5 x 13 = 260
The prime factors of 86 are: 2 43
143 is composite because it has more than 2 factors. Any number with exactly 2 factors (1 and the number itself) is prime. The factors of 143 are 1, 11, 13, and 143.
Since both 11 and 13 are prime numbers, the LCM of these 2 number is 11 * 13 = 143. All multiples of 143 are multiples of 11 and 13 as well
No, 14 is a multiple of 7. 7 is a factor of 14.
The factors of 286 are 1, 2, 11, 13, 22, 26, 143, and 286. The prime factors of 286 are 2 x 11 x 13.
