Given numbers are 748,715,251,286,818
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 748,715,251,286,818 is 4991280580.
Find LCM of 748,715,251,286,818 with Prime Factorization
| 2 | 748, 715, 251, 286, 818 |
| 11 | 374, 715, 251, 143, 409 |
| 13 | 34, 65, 251, 13, 409 |
| 34, 5, 251, 1, 409 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 13 x 34 x 5 x 251 x 1 x 409 = 4991280580
Therefore, the lowest common multiple of 748,715,251,286,818 is 4991280580.
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.
748 x 715 x 251 x 286 x 818 = 31405137409360
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.
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
715 : 1, 5, 11, 13, 55, 65, 143, 715
251 : 1, 251
286 : 1, 2, 11, 13, 22, 26, 143, 286
818 : 1, 2, 409, 818
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 748,715,251,286,818, is 1.
Now, the common factors can be found like this.
748:2x 2x 11x 17
715:5x 11x 13
251:251
286:2x 11x 13
818:2x 409
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 11x 11x 13 = 6292
Therefore, the value for common factors is 6292.
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 = 31405137409360/(1x6292)
LCM = 31405137409360/6292
LCM = 4991280580
Thus, we can understand that the LCM of 748,715,251,286,818 is 4991280580.
