Given numbers are 993,390,838,642,478
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 993,390,838,642,478 is 1383210580830.
Find LCM of 993,390,838,642,478 with Prime Factorization
2 | 993, 390, 838, 642, 478 |
3 | 993, 195, 419, 321, 239 |
331, 65, 419, 107, 239 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 331 x 65 x 419 x 107 x 239 = 1383210580830
Therefore, the lowest common multiple of 993,390,838,642,478 is 1383210580830.
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.
993 x 390 x 838 x 642 x 478 = 99591161819760
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.
993 : 1, 3, 331, 993
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
838 : 1, 2, 419, 838
642 : 1, 2, 3, 6, 107, 214, 321, 642
478 : 1, 2, 239, 478
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 993,390,838,642,478, is 1.
Now, the common factors can be found like this.
993:3x 331
390:2x 3x 5x 13
838:2x 419
642:2x 3x 107
478:2x 239
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 3 = 72
Therefore, the value for common factors is 72.
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 = 99591161819760/(1x72)
LCM = 99591161819760/72
LCM = 1383210580830
Thus, we can understand that the LCM of 993,390,838,642,478 is 1383210580830.
