Given numbers are 424,818,715,897
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 424,818,715,897 is 8555478360.
Find LCM of 424,818,715,897 with Prime Factorization
| 2 | 424, 818, 715, 897 |
| 13 | 212, 409, 715, 897 |
| 212, 409, 55, 69 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 212 x 409 x 55 x 69 = 8555478360
Therefore, the lowest common multiple of 424,818,715,897 is 8555478360.
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.
424 x 818 x 715 x 897 = 222442437360
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.
424 : 1, 2, 4, 8, 53, 106, 212, 424
818 : 1, 2, 409, 818
715 : 1, 5, 11, 13, 55, 65, 143, 715
897 : 1, 3, 13, 23, 39, 69, 299, 897
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 424,818,715,897, is 1.
Now, the common factors can be found like this.
424:2x 2x 2x 53
818:2x 409
715:5x 11x 13
897:3x 13x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13 = 26
Therefore, the value for common factors is 26.
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 = 222442437360/(1x26)
LCM = 222442437360/26
LCM = 8555478360
Thus, we can understand that the LCM of 424,818,715,897 is 8555478360.
