Given numbers are 655,744,285,934,915
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 655,744,285,934,915 is 263763411960.
Find LCM of 655,744,285,934,915 with Prime Factorization
| 2 | 655, 744, 285, 934, 915 |
| 3 | 655, 372, 285, 467, 915 |
| 5 | 655, 124, 95, 467, 305 |
| 131, 124, 19, 467, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 131 x 124 x 19 x 467 x 61 = 263763411960
Therefore, the lowest common multiple of 655,744,285,934,915 is 263763411960.
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.
655 x 744 x 285 x 934 x 915 = 118693535382000
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.
655 : 1, 5, 131, 655
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
285 : 1, 3, 5, 15, 19, 57, 95, 285
934 : 1, 2, 467, 934
915 : 1, 3, 5, 15, 61, 183, 305, 915
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,744,285,934,915, is 1.
Now, the common factors can be found like this.
655:5x 131
744:2x 2x 2x 3x 31
285:3x 5x 19
934:2x 467
915:3x 5x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5x 5 = 450
Therefore, the value for common factors is 450.
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 = 118693535382000/(1x450)
LCM = 118693535382000/450
LCM = 263763411960
Thus, we can understand that the LCM of 655,744,285,934,915 is 263763411960.
