Given numbers are 801,812,638,175
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 801,812,638,175 is 178863300.
Find LCM of 801,812,638,175 with Prime Factorization
| 2 | 801, 812, 638, 175 |
| 7 | 801, 406, 319, 175 |
| 29 | 801, 58, 319, 25 |
| 801, 2, 11, 25 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 29 x 801 x 2 x 11 x 25 = 178863300
Therefore, the lowest common multiple of 801,812,638,175 is 178863300.
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.
801 x 812 x 638 x 175 = 72618499800
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.
801 : 1, 3, 9, 89, 267, 801
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
638 : 1, 2, 11, 22, 29, 58, 319, 638
175 : 1, 5, 7, 25, 35, 175
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 801,812,638,175, is 1.
Now, the common factors can be found like this.
801:3x 3x 89
812:2x 2x 7x 29
638:2x 11x 29
175:5x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 29 = 406
Therefore, the value for common factors is 406.
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 = 72618499800/(1x406)
LCM = 72618499800/406
LCM = 178863300
Thus, we can understand that the LCM of 801,812,638,175 is 178863300.
