Given numbers are 730,502,858,390,120
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 730,502,858,390,120 is 314422680.
Find LCM of 730,502,858,390,120 with Prime Factorization
| 2 | 730, 502, 858, 390, 120 |
| 3 | 365, 251, 429, 195, 60 |
| 5 | 365, 251, 143, 65, 20 |
| 13 | 73, 251, 143, 13, 4 |
| 73, 251, 11, 1, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 73 x 251 x 11 x 1 x 4 = 314422680
Therefore, the lowest common multiple of 730,502,858,390,120 is 314422680.
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.
730 x 502 x 858 x 390 x 120 = 14714981424000
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.
730 : 1, 2, 5, 10, 73, 146, 365, 730
502 : 1, 2, 251, 502
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 730,502,858,390,120, is 2.
Now, the common factors can be found like this.
730:2x 5x 73
502:2x 251
858:2x 3x 11x 13
390:2x 3x 5x 13
120:2x 2x 2x 3x 5
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 2x 3x 3x 5x 5x 13 = 23400
Therefore, the value for common factors is 23400.
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 = 14714981424000/(2x23400)
LCM = 14714981424000/46800
LCM = 314422680
Thus, we can understand that the LCM of 730,502,858,390,120 is 314422680.
