Find LCM of 635,642,428,975,826 with Prime Factorization
| 2 | 635, 642, 428, 975, 826 |
| 3 | 635, 321, 214, 975, 413 |
| 5 | 635, 107, 214, 325, 413 |
| 107 | 127, 107, 214, 65, 413 |
| 127, 1, 2, 65, 413 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 107 x 127 x 1 x 2 x 65 x 413 = 21887802300
Therefore, the lowest common multiple of 635,642,428,975,826 is 21887802300.
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.
635 x 642 x 428 x 975 x 826 = 140519690766000
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.
635 : 1, 5, 127, 635
642 : 1, 2, 3, 6, 107, 214, 321, 642
428 : 1, 2, 4, 107, 214, 428
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
826 : 1, 2, 7, 14, 59, 118, 413, 826
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 635,642,428,975,826, is 1.
Now, the common factors can be found like this.
635:5x 127
642:2x 3x 107
428:2x 2x 107
975:3x 5x 5x 13
826:2x 7x 59
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 3x 5x 107 = 6420
Therefore, the value for common factors is 6420.
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 = 140519690766000/(1x6420)
LCM = 140519690766000/6420
LCM = 21887802300
Thus, we can understand that the LCM of 635,642,428,975,826 is 21887802300.
