Given numbers are 524,638,646,956,288
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 524,638,646,956,288 is 929083804704.
Find LCM of 524,638,646,956,288 with Prime Factorization
| 2 | 524, 638, 646, 956, 288 |
| 2 | 262, 319, 323, 478, 144 |
| 131, 319, 323, 239, 72 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 131 x 319 x 323 x 239 x 72 = 929083804704
Therefore, the lowest common multiple of 524,638,646,956,288 is 929083804704.
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.
524 x 638 x 646 x 956 x 288 = 59461363501056
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.
524 : 1, 2, 4, 131, 262, 524
638 : 1, 2, 11, 22, 29, 58, 319, 638
646 : 1, 2, 17, 19, 34, 38, 323, 646
956 : 1, 2, 4, 239, 478, 956
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 524,638,646,956,288, is 2.
Now, the common factors can be found like this.
524:2x 2x 131
638:2x 11x 29
646:2x 17x 19
956:2x 2x 239
288:2x 2x 2x 2x 2x 3x 3
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 2 = 32
Therefore, the value for common factors is 32.
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 = 59461363501056/(2x32)
LCM = 59461363501056/64
LCM = 929083804704
Thus, we can understand that the LCM of 524,638,646,956,288 is 929083804704.
