I Dont know if this is for prime's or not but i can remember doing this thing.
you add up the numbers of the digit ( 4+2+9=15) Then You see if 15 is a prime then you have the answer. ================================ 429 = 3*11*13. Hence, it is not a Prime number. A comment on the first author's response: 37 is a prime number. The sum of 3 and 7 is 10. Ten is not a prime number. Hence the rule does not apply universally. The rule does not apply to 11, 13, ,17, or 19, all known prime numbers, either. I find the related link to be useful.
================================
As a product of its prime factors: 3*11*13 = 429
As a product of its prime factors: 429 = 3*11*13
33 = 3 x 11 39 = 3 x 13 Note that there are 3 columns ( 3, 11, 13) and they are all prime numbers (prime factorisation) To find the LCM, multiply the highest number in each column, so, 3 x 11 x 13 = 429 So, the LCM is 429
110 percent of 390 =429 110% of 390 = 110% * 390 = 110%/100% * 390 = 429/1 or 429
35% of 429 = 35% * 429 = 0.35 * 429 = 150.15
No 429 is not prime. A prime number is a number where the only multiples of it are "1" and the number itself. 429 / 3 = 143. So 3 x 143 are also factors.Prime numbers do not end in 0,2,4,5,6,8; excluding 2 (Two), 22 is not prime but 2 is because 1 x 2 = 2. And remember the definition says a prime number is a number that can only be multiplied by 1 and itself.
As a product of its prime factors: 3*11*13 = 429
As a product of its prime factors: 429 = 3*11*13
3 x 11 x 13 = 429
3 x 11 x 13 = 429
No, 429 is an odd number.
429 is a composite number because it has factors other than 1 and itself. It is not a prime number.The 8 factors of 429 are 1, 3, 11, 13, 33, 39, 143, and 429.The factor pairs of 429 are 1 x 429, 3 x 143, 11 x 39, and 13 x 33.The proper factors of 429 are 1, 3, 11, 13, 33, 39, and 143 or,if the definition you are using excludes 1, they are 3, 11, 13, 33, 39, and 143.The prime factors of 429 are 3, 11, and 13.The 2 distinct prime factors (listing each prime factor only once) of 429 are 3, 11, and 13.The prime factorization of 429 is 3 x 11 x 13.NOTE: There cannot be common factors, a greatest common factor, or a least common multiple because "common" refers to factors or multiples that two or more numbers have in common.
429 is a composite number because it is divisible by 3 in addition to 1 and itself. It is easy to tell that it is divisible by three because the sum of its digits is divisible by 3: 4 + 2 + 9 = 15.
429 over 5 as a mixed number is: 854/5
3 x 11 x 13
The GCF of 429 and 507 is 39. The prime factorization of 507 is 3 x 13 x 13 The prime factorization of 429 is 3 x 11 x 13; THe common factors are 3 & 13 so the GCF is 39
To find 65 percent of a number, multiply the number by 0.65. In this instance, 0.65 x 429 = 278.85. Therefore, 65 percent of 429 is equal to 278.85.
