Given numbers are 708,665,646,902,513
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 708,665,646,902,513 is 32487992460.
Find LCM of 708,665,646,902,513 with Prime Factorization
| 2 | 708, 665, 646, 902, 513 |
| 3 | 354, 665, 323, 451, 513 |
| 19 | 118, 665, 323, 451, 171 |
| 118, 35, 17, 451, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 118 x 35 x 17 x 451 x 9 = 32487992460
Therefore, the lowest common multiple of 708,665,646,902,513 is 32487992460.
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.
708 x 665 x 646 x 902 x 513 = 140737983336720
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.
708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708
665 : 1, 5, 7, 19, 35, 95, 133, 665
646 : 1, 2, 17, 19, 34, 38, 323, 646
902 : 1, 2, 11, 22, 41, 82, 451, 902
513 : 1, 3, 9, 19, 27, 57, 171, 513
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 708,665,646,902,513, is 1.
Now, the common factors can be found like this.
708:2x 2x 3x 59
665:5x 7x 19
646:2x 17x 19
902:2x 11x 41
513:3x 3x 3x 19
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 19x 19 = 4332
Therefore, the value for common factors is 4332.
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 = 140737983336720/(1x4332)
LCM = 140737983336720/4332
LCM = 32487992460
Thus, we can understand that the LCM of 708,665,646,902,513 is 32487992460.
