Given numbers are 278,715,225,650
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 278,715,225,650 is 8944650.
Find LCM of 278,715,225,650 with Prime Factorization
| 2 | 278, 715, 225, 650 |
| 5 | 139, 715, 225, 325 |
| 5 | 139, 143, 45, 65 |
| 13 | 139, 143, 9, 13 |
| 139, 11, 9, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 5 x 13 x 139 x 11 x 9 x 1 = 8944650
Therefore, the lowest common multiple of 278,715,225,650 is 8944650.
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.
278 x 715 x 225 x 650 = 29070112500
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.
278 : 1, 2, 139, 278
715 : 1, 5, 11, 13, 55, 65, 143, 715
225 : 1, 3, 5, 9, 15, 25, 45, 75, 225
650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,715,225,650, is 1.
Now, the common factors can be found like this.
278:2x 139
715:5x 11x 13
225:3x 3x 5x 5
650:2x 5x 5x 13
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 5x 5x 13 = 3250
Therefore, the value for common factors is 3250.
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 = 29070112500/(1x3250)
LCM = 29070112500/3250
LCM = 8944650
Thus, we can understand that the LCM of 278,715,225,650 is 8944650.
