Given numbers are 310,210,909,143,390
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 310,210,909,143,390 is 282071790.
Find LCM of 310,210,909,143,390 with Prime Factorization
| 2 | 310, 210, 909, 143, 390 |
| 3 | 155, 105, 909, 143, 195 |
| 5 | 155, 35, 303, 143, 65 |
| 13 | 31, 7, 303, 143, 13 |
| 31, 7, 303, 11, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 31 x 7 x 303 x 11 x 1 = 282071790
Therefore, the lowest common multiple of 310,210,909,143,390 is 282071790.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
310 x 210 x 909 x 143 x 390 = 3300239943000
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
310 : 1, 2, 5, 10, 31, 62, 155, 310
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
909 : 1, 3, 9, 101, 303, 909
143 : 1, 11, 13, 143
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 310,210,909,143,390, is 1.
Now, the common factors can be found like this.
310:2x 5x 31
210:2x 3x 5x 7
909:3x 3x 101
143:11x 13
390:2x 3x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 5x 5x 13 = 11700
Therefore, the value for common factors is 11700.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 3300239943000/(1x11700)
LCM = 3300239943000/11700
LCM = 282071790
Thus, we can understand that the LCM of 310,210,909,143,390 is 282071790.
