The LCM of 675,825,632,642 is 502108200.
Find LCM of 675,825,632,642 with Prime Factorization
| 2 | 675, 825, 632, 642 |
| 3 | 675, 825, 316, 321 |
| 5 | 225, 275, 316, 107 |
| 5 | 45, 55, 316, 107 |
| 9, 11, 316, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 5 x 9 x 11 x 316 x 107 = 502108200
Therefore, the lowest common multiple of 675,825,632,642 is 502108200.
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.
675 x 825 x 632 x 642 = 225948690000
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.
675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675
825 : 1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825
632 : 1, 2, 4, 8, 79, 158, 316, 632
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 675,825,632,642, is 1.
Now, the common factors can be found like this.
675:3x 3x 3x 5x 5
825:3x 5x 5x 11
632:2x 2x 2x 79
642:2x 3x 107
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 3x 5x 5 = 450
Therefore, the value for common factors is 450.
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 = 225948690000/(1x450)
LCM = 225948690000/450
LCM = 502108200
Thus, we can understand that the LCM of 675,825,632,642 is 502108200.
