Given numbers are 799,680,354,385
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 799,680,354,385 is 435582840.
Find LCM of 799,680,354,385 with Prime Factorization
| 2 | 799, 680, 354, 385 |
| 5 | 799, 340, 177, 385 |
| 17 | 799, 68, 177, 77 |
| 47, 4, 177, 77 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 47 x 4 x 177 x 77 = 435582840
Therefore, the lowest common multiple of 799,680,354,385 is 435582840.
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.
799 x 680 x 354 x 385 = 74049082800
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.
799 : 1, 17, 47, 799
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
354 : 1, 2, 3, 6, 59, 118, 177, 354
385 : 1, 5, 7, 11, 35, 55, 77, 385
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 799,680,354,385, is 1.
Now, the common factors can be found like this.
799:17x 47
680:2x 2x 2x 5x 17
354:2x 3x 59
385:5x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 17 = 170
Therefore, the value for common factors is 170.
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 = 74049082800/(1x170)
LCM = 74049082800/170
LCM = 435582840
Thus, we can understand that the LCM of 799,680,354,385 is 435582840.
