None of the numbers 7, 11, and 13 are composite numbers; they are all primes.
The numbers 11, 13, 17 and 19 are prime.
101
11 and 13
11 13 17 19.
They are all odd, and they are all prime numbers
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
The least common multiple of the numbers 11, 12 and 13 is 1,716.
One thing that they have in common is that they are all integers.
None of the numbers 7, 11, and 13 are composite numbers; they are all primes.
1
The only common factor of these numbers is 1.
Factor the numbers into primes: 55 = 5 * 11 143 = 13 * 11 110 = 2 * 5 * 11 The ONLY factor they all have in common is 11. 11 is the greatest (and only) common factor.
The prime numbers from 1 to 13 are 2, 3, 5, 7, 11, and 13.
The least common multiple of 5 , 7 , 11 , 13 , 8 = 40,040
The GCF of 143 and 169 is 13. One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 143 are 1, 11, 13, and 143. The factors of 169 are 1, 13, and 169. The common factors are 1 and 13. Therefore, the greatest common factor is 13.
The numbers 11, 13, 17 and 19 are prime.
