Given numbers are 424,670,715,400
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 424,670,715,400 is 203117200.
Find LCM of 424,670,715,400 with Prime Factorization
| 2 | 424, 670, 715, 400 |
| 2 | 212, 335, 715, 200 |
| 2 | 106, 335, 715, 100 |
| 5 | 53, 335, 715, 50 |
| 53, 67, 143, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 53 x 67 x 143 x 10 = 203117200
Therefore, the lowest common multiple of 424,670,715,400 is 203117200.
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.
424 x 670 x 715 x 400 = 81246880000
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.
424 : 1, 2, 4, 8, 53, 106, 212, 424
670 : 1, 2, 5, 10, 67, 134, 335, 670
715 : 1, 5, 11, 13, 55, 65, 143, 715
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 424,670,715,400, is 1.
Now, the common factors can be found like this.
424:2x 2x 2x 53
670:2x 5x 67
715:5x 11x 13
400:2x 2x 2x 2x 5x 5
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 2x 5x 5 = 400
Therefore, the value for common factors is 400.
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 = 81246880000/(1x400)
LCM = 81246880000/400
LCM = 203117200
Thus, we can understand that the LCM of 424,670,715,400 is 203117200.
