The factorizations of both numbers use 2 and 5, and each has only two other factors (for 220, 2 and 11 - for 390, 3 and 13, which represent the primes immediately following the ones for 220).
390 = 2*3*5*13
2 x 3 x 5 x 13 = 390 No exponents necessary.
The prime factors of 390 are: 2, 3, 5, and 13.is 390 a prime number
factorization: 78=2*3*13 65=5*13 LCM=2*3*5*13=390
2 x 3 x 5 x 13 = 390
390 = 2*3*5*13
2 x 3 x 5 x 15 = 390
2 and 5
220=2,2,5,11 390=2,3,5,13 They both share 2 and 5.
Decimals can not be factorised but if you mean 390 then it is:- 2*3*5*13 = 390
390/\30 × 13/\15 × 2/\5 × 35 × 3 × 2 × 13
The prime factors are: 2 x 3 x 5 x 13
2 x 3 x 5 x 13 = 390 No exponents necessary.
The prime factors of 390 are: 2, 3, 5, and 13.is 390 a prime number
Well, honey, the least common multiple (LCM) of 260 and 390 is 780. You see, 260 is 2 times 2 times 5 times 13, while 390 is 2 times 3 times 5 times 13. So, the LCM is just the product of all the unique prime factors with the highest power they appear in either number. Easy peasy lemon squeezy!
To express 390 as a product of prime factors, we first divide it by the smallest prime number, which is 2. This gives us 195. Next, we divide 195 by 3 to get 65. Continuing this process, we divide 65 by 5 to get 13. Since 13 is a prime number, the prime factorization of 390 is 2 x 3 x 5 x 13.
To find the Least Common Multiple (LCM) of 130 and 195, you first need to find the prime factorization of each number. The prime factorization of 130 is 2 x 5 x 13, and the prime factorization of 195 is 3 x 5 x 13. Then, you identify the common prime factors and their highest powers, which are 2, 3, 5, and 13. Finally, you multiply these common prime factors with their highest powers to find the LCM, which is 2 x 3 x 5 x 13 = 390.
