Given numbers are 441,553,159,631,455
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 441,553,159,631,455 is 75732844005.
Find LCM of 441,553,159,631,455 with Prime Factorization
| 3 | 441, 553, 159, 631, 455 |
| 7 | 147, 553, 53, 631, 455 |
| 21, 79, 53, 631, 65 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 21 x 79 x 53 x 631 x 65 = 75732844005
Therefore, the lowest common multiple of 441,553,159,631,455 is 75732844005.
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.
441 x 553 x 159 x 631 x 455 = 11132728068735
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.
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
553 : 1, 7, 79, 553
159 : 1, 3, 53, 159
631 : 1, 631
455 : 1, 5, 7, 13, 35, 65, 91, 455
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 441,553,159,631,455, is 1.
Now, the common factors can be found like this.
441:3x 3x 7x 7
553:7x 79
159:3x 53
631:631
455:5x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 7 = 147
Therefore, the value for common factors is 147.
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 = 11132728068735/(1x147)
LCM = 11132728068735/147
LCM = 75732844005
Thus, we can understand that the LCM of 441,553,159,631,455 is 75732844005.
