Given numbers are 390,722,382,931,464
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 390,722,382,931,464 is 305695637520.
Find LCM of 390,722,382,931,464 with Prime Factorization
| 2 | 390, 722, 382, 931, 464 |
| 19 | 195, 361, 191, 931, 232 |
| 195, 19, 191, 49, 232 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 195 x 19 x 191 x 49 x 232 = 305695637520
Therefore, the lowest common multiple of 390,722,382,931,464 is 305695637520.
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.
390 x 722 x 382 x 931 x 464 = 46465736903040
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.
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
722 : 1, 2, 19, 38, 361, 722
382 : 1, 2, 191, 382
931 : 1, 7, 19, 49, 133, 931
464 : 1, 2, 4, 8, 16, 29, 58, 116, 232, 464
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,722,382,931,464, is 1.
Now, the common factors can be found like this.
390:2x 3x 5x 13
722:2x 19x 19
382:2x 191
931:7x 7x 19
464:2x 2x 2x 2x 29
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 19 = 152
Therefore, the value for common factors is 152.
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 = 46465736903040/(1x152)
LCM = 46465736903040/152
LCM = 305695637520
Thus, we can understand that the LCM of 390,722,382,931,464 is 305695637520.
