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
factorization: 78=2*3*13 65=5*13 LCM=2*3*5*13=390
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.
The greatest common factor of 180 and 390 is 30.
