2 x 3 x 5 x 13 = 390
No exponents necessary.
390 = 2*3*5*13
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).
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
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

780 is a composite number because it has factors other than 1 and itself. It is not a prime number.The 24 factors of 780 are 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, and 780.The proper factors of 780 are 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, and 390 or,if the definition you are using excludes 1, they are 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, and 390.The prime factors of 780 are 2, 2, 3, 5, and 13. Note: There is repetition of these factors, so if the prime factors are being listed instead of the prime factorization, usually only the distinct prime factors are listed.The 4 distinct prime factors (listing each prime factor only once) of 780 are 2, 3, 5, and 13.The prime factorization of 780 is 2 x 2 x 3 x 5 x 13 or, in index form (in other words, using exponents), 22 x 3 x 5 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.
