Given numbers are 724,940,740,490,934
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 724,940,740,490,934 is 144052603940.
Find LCM of 724,940,740,490,934 with Prime Factorization
| 2 | 724, 940, 740, 490, 934 |
| 2 | 362, 470, 370, 245, 467 |
| 5 | 181, 235, 185, 245, 467 |
| 181, 47, 37, 49, 467 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 181 x 47 x 37 x 49 x 467 = 144052603940
Therefore, the lowest common multiple of 724,940,740,490,934 is 144052603940.
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.
724 x 940 x 740 x 490 x 934 = 230484166304000
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.
724 : 1, 2, 4, 181, 362, 724
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
934 : 1, 2, 467, 934
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 724,940,740,490,934, is 2.
Now, the common factors can be found like this.
724:2x 2x 181
940:2x 2x 5x 47
740:2x 2x 5x 37
490:2x 5x 7x 7
934:2x 467
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 2x 5x 5 = 800
Therefore, the value for common factors is 800.
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 = 230484166304000/(2x800)
LCM = 230484166304000/1600
LCM = 144052603940
Thus, we can understand that the LCM of 724,940,740,490,934 is 144052603940.
