3 x 3 = 9
answer the question
Optimus Prime has 10 brothers. The dynasty of primes (9) and Megatron
Two numbers are said to be co-primes if they do not share any common divisor except for 1. For example, 9 and 10 are co-primes. Number 9 has factors 1,3,9 and 10 has 1,2,5,10. Only 1 is common. So, these two are co-prime numbers.
3x3
The numbers 11 and 13 are prime twins. Prime twins are consecutive prime numbers that differ by a difference of two. For example, 3 and 5, 7 and 9 are twin primes.
The question is misguided. The word "February" has no primes. The month of February has 28 (or 29) days and, of these, 9 (or 10) are prime.
no if you multiply two primes for example 7x9=63 63 is not prime because 9 and 7 go into it
HCF is the highest common factor of two or more numbers. As they 9 and 11 are co-primes hence HCF is 1.
The GCF of 18 and 63 is 9.The factors of 63 are: 1, 3, 7, 9, 21, & 63The factors of 18 are: 1, 2, 3, 6, 9, & 18The GCF (AKA Greatest Common Factor) is 9.Using prime factorization for 18 you get 2, and two 3's as your primes. For 63 you get 7, and two 3's as your primes. As the two 3's are in common you between both of the numbers, you do 3 multiplied by 3 which is 9. Therefore the gcf for 18, and 63 is 9.The GCF is 9.
HELLO There is NO world 9.(btw I checked another 'world nine' question and there IS!! On the wii!)
This question is on my daughter's homework--Which shows 45 as a product of primes? (A) 15 x 3 (B) 3 x 5 x 3 (C) 1 x 5 x 9 (D) 1 x 3 x 15 Please help B. 3 and 5 are primes. Reject: A and D: 15 = 3*5 and so 15 is not prime. C: 9 = 3*3 and so 9 is not a prime.
