Given numbers are 708,671,845,280,450
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 708,671,845,280,450 is 84300816600.
Find LCM of 708,671,845,280,450 with Prime Factorization
| 2 | 708, 671, 845, 280, 450 |
| 2 | 354, 671, 845, 140, 225 |
| 3 | 177, 671, 845, 70, 225 |
| 5 | 59, 671, 845, 70, 75 |
| 59, 671, 169, 14, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 59 x 671 x 169 x 14 x 15 = 84300816600
Therefore, the lowest common multiple of 708,671,845,280,450 is 84300816600.
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.
708 x 671 x 845 x 280 x 450 = 50580489960000
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.
708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708
671 : 1, 11, 61, 671
845 : 1, 5, 13, 65, 169, 845
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 708,671,845,280,450, is 1.
Now, the common factors can be found like this.
708:2x 2x 3x 59
671:11x 61
845:5x 13x 13
280:2x 2x 2x 5x 7
450:2x 3x 3x 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 3x 5x 5 = 600
Therefore, the value for common factors is 600.
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 = 50580489960000/(1x600)
LCM = 50580489960000/600
LCM = 84300816600
Thus, we can understand that the LCM of 708,671,845,280,450 is 84300816600.
