Given numbers are 454,472,921,814,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 454,472,921,814,561 is 682764318456.
Find LCM of 454,472,921,814,561 with Prime Factorization
| 2 | 454, 472, 921, 814, 561 |
| 3 | 227, 236, 921, 407, 561 |
| 11 | 227, 236, 307, 407, 187 |
| 227, 236, 307, 37, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 227 x 236 x 307 x 37 x 17 = 682764318456
Therefore, the lowest common multiple of 454,472,921,814,561 is 682764318456.
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.
454 x 472 x 921 x 814 x 561 = 90124890036192
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.
454 : 1, 2, 227, 454
472 : 1, 2, 4, 8, 59, 118, 236, 472
921 : 1, 3, 307, 921
814 : 1, 2, 11, 22, 37, 74, 407, 814
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 454,472,921,814,561, is 1.
Now, the common factors can be found like this.
454:2x 227
472:2x 2x 2x 59
921:3x 307
814:2x 11x 37
561:3x 11x 17
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 3x 11 = 132
Therefore, the value for common factors is 132.
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 = 90124890036192/(1x132)
LCM = 90124890036192/132
LCM = 682764318456
Thus, we can understand that the LCM of 454,472,921,814,561 is 682764318456.
