Given numbers are 287,986,717,735,478
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 287,986,717,735,478 is 7101433290.
Find LCM of 287,986,717,735,478 with Prime Factorization
| 2 | 287, 986, 717, 735, 478 |
| 3 | 287, 493, 717, 735, 239 |
| 7 | 287, 493, 239, 245, 239 |
| 239 | 41, 493, 239, 35, 239 |
| 41, 493, 1, 35, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 239 x 41 x 493 x 1 x 35 x 1 = 7101433290
Therefore, the lowest common multiple of 287,986,717,735,478 is 7101433290.
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.
287 x 986 x 717 x 735 x 478 = 71284187365020
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.
287 : 1, 7, 41, 287
986 : 1, 2, 17, 29, 34, 58, 493, 986
717 : 1, 3, 239, 717
735 : 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735
478 : 1, 2, 239, 478
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 287,986,717,735,478, is 1.
Now, the common factors can be found like this.
287:7x 41
986:2x 17x 29
717:3x 239
735:3x 5x 7x 7
478:2x 239
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 7x 239 = 10038
Therefore, the value for common factors is 10038.
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 = 71284187365020/(1x10038)
LCM = 71284187365020/10038
LCM = 7101433290
Thus, we can understand that the LCM of 287,986,717,735,478 is 7101433290.
