Given numbers are 901,910,629,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 901,910,629,642 is 9738071070.
Find LCM of 901,910,629,642 with Prime Factorization
| 2 | 901, 910, 629, 642 |
| 17 | 901, 455, 629, 321 |
| 53, 455, 37, 321 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 53 x 455 x 37 x 321 = 9738071070
Therefore, the lowest common multiple of 901,910,629,642 is 9738071070.
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.
901 x 910 x 629 x 642 = 331094416380
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.
901 : 1, 17, 53, 901
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
629 : 1, 17, 37, 629
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 901,910,629,642, is 1.
Now, the common factors can be found like this.
901:17x 53
910:2x 5x 7x 13
629:17x 37
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 17 = 34
Therefore, the value for common factors is 34.
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 = 331094416380/(1x34)
LCM = 331094416380/34
LCM = 9738071070
Thus, we can understand that the LCM of 901,910,629,642 is 9738071070.
