Find LCM of 825,555,668,245,490 with Prime Factorization
| 2 | 825, 555, 668, 245, 490 |
| 3 | 825, 555, 334, 245, 245 |
| 5 | 275, 185, 334, 245, 245 |
| 7 | 55, 37, 334, 49, 49 |
| 7 | 55, 37, 334, 7, 7 |
| 55, 37, 334, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 7 x 55 x 37 x 334 x 1 x 1 = 999144300
Therefore, the lowest common multiple of 825,555,668,245,490 is 999144300.
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.
825 x 555 x 668 x 245 x 490 = 36718553025000
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.
825 : 1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825
555 : 1, 3, 5, 15, 37, 111, 185, 555
668 : 1, 2, 4, 167, 334, 668
245 : 1, 5, 7, 35, 49, 245
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 825,555,668,245,490, is 1.
Now, the common factors can be found like this.
825:3x 5x 5x 11
555:3x 5x 37
668:2x 2x 167
245:5x 7x 7
490:2x 5x 7x 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 3x 5x 5x 5x 7x 7 = 36750
Therefore, the value for common factors is 36750.
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 = 36718553025000/(1x36750)
LCM = 36718553025000/36750
LCM = 999144300
Thus, we can understand that the LCM of 825,555,668,245,490 is 999144300.
