Given numbers are 815,652,798,437
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 815,652,798,437 is 29917020.
Find LCM of 815,652,798,437 with Prime Factorization
| 2 | 815, 652, 798, 437 |
| 19 | 815, 326, 399, 437 |
| 163 | 815, 326, 21, 23 |
| 5, 2, 21, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 163 x 5 x 2 x 21 x 23 = 29917020
Therefore, the lowest common multiple of 815,652,798,437 is 29917020.
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.
815 x 652 x 798 x 437 = 185306021880
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.
815 : 1, 5, 163, 815
652 : 1, 2, 4, 163, 326, 652
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
437 : 1, 19, 23, 437
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,652,798,437, is 1.
Now, the common factors can be found like this.
815:5x 163
652:2x 2x 163
798:2x 3x 7x 19
437:19x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 19x 163 = 6194
Therefore, the value for common factors is 6194.
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 = 185306021880/(1x6194)
LCM = 185306021880/6194
LCM = 29917020
Thus, we can understand that the LCM of 815,652,798,437 is 29917020.
