Given numbers are 753,852,408,660
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 753,852,408,660 is 399903240.
Find LCM of 753,852,408,660 with Prime Factorization
| 2 | 753, 852, 408, 660 |
| 2 | 753, 426, 204, 330 |
| 3 | 753, 213, 102, 165 |
| 251, 71, 34, 55 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 251 x 71 x 34 x 55 = 399903240
Therefore, the lowest common multiple of 753,852,408,660 is 399903240.
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.
753 x 852 x 408 x 660 = 172758199680
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.
753 : 1, 3, 251, 753
852 : 1, 2, 3, 4, 6, 12, 71, 142, 213, 284, 426, 852
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 753,852,408,660, is 3.
Now, the common factors can be found like this.
753:3x 251
852:2x 2x 3x 71
408:2x 2x 2x 3x 17
660:2x 2x 3x 5x 11
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 2x 2x 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 172758199680/(3x144)
LCM = 172758199680/432
LCM = 399903240
Thus, we can understand that the LCM of 753,852,408,660 is 399903240.
