220=2,2,5,11
390=2,3,5,13
They both share 2 and 5.
2 and 5
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 common factors are 1, 3, 5, 15.
The prime factors of 390 are: 2, 3, 5, and 13.is 390 a prime number

Yes, 390 is a composite number. It has factors other than 1 and 390. The factors of 390 are 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, and 390.
Least common multiple of 65 and 78 is 390.
The positive integer factors of 390 are: 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
The greatest common factor of 390 and 2431= =13
The GCF of 48 and 390 is 6.
To find the LCM of these numbers, you have to split them into their prime factors: 15 = 3x5 26 = 2x13 The next step would be to identify any common prime factors. However in this case there are none. Thus to find the LCM you just multiply the two numbers together: 15x26 = 390 And so the LCM of 15 and 26 is 390.
