No, the only even prime number is 2.

composite.

No, 142 is not prime.

In order to get three prime numbers to add up to an even number, one of them will have to be even. The only even prime number is 2.144 - 2 = 142.You need to find 2 prime numbers that can add up to 142. 71 is prime and added to itself will be 142, but that won't give you three different prime numbers.Use a list of prime numbers and subtract each prime that is greater than 71 (fewer than primes less than 71) from 142 to see if the difference is another prime:142 - 73 = 69 (not prime)142 - 79 = 63 (not prime)142 - 83 = 59 (prime)142 - 89 = 53 (prime)142 - 97 = 45 (not prime)142 - 101 = 41 (prime)142 - 103 = 39 (not prime)142 - 107 = 35 (not prime)142 - 109 = 33 (not prime)142 - 113 = 29 (prime)142 - 127 = 15 (not prime)142 - 131 = 11 (prime)142 - 137 = 5 (prime)142 - 139 = 3 (prime)You end up with 7 sets of 3 prime numbers that add up to 144:2, 59, 832, 53, 892, 41, 1012, 29, 1132, 11, 1312, 5, 1372, 3, 139

142 is a composite number; it has factors other than 1 and itself.The four factors of 142 are 1, 2, 71, 142.The factor pairs of 142 are 1 x 142 and 2 x 71.The proper factors of 142 are 1, 2, and 71 or,if the definition you are using excludes 1, they are 2 and 71.The prime factors of 142 are 2 and 71The distinct prime factors of 142 are also 2 and 71 since there is no repetition of factors.The prime factorization of 142 is 2 x 71.

2 * 71 = 142 both 2 and 71 are prime

1, 2, 71, 142 2 and 71 are prime.

142 = 2 * 71

Start with the prime factorization. 2 x 71 = 142 Any number with two distinct prime factors has four factors in total. Since it's automatic that one and the number itself are included, you have them all. 1, 2, 71, 142

142 = 2 x 71

It is: 2*71 = 142

Composite. It is an even number after all, so the factor 2 is a given.

142 = 21 x 711

no you can divide it by 71 and 2 and both of those are prime

As a product of its prime factors: 2*71 = 142

2, 71

The factors of 142 are: 1, 2, 71, and 142. The prime factors of 142 are: 2 and 71. The factors of 148 are: 1, 2, 4, 37, 74, and 148. The prime factors of 148 are: 2 and 37.

1. 13 is a prime number, so it has only 1 and 13 as its factors, and 142 can't be divided by 13, so the GCF here is 1.
