Given numbers are 454,391,578,855,197
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 454,391,578,855,197 is 508292700030.
Find LCM of 454,391,578,855,197 with Prime Factorization
| 2 | 454, 391, 578, 855, 197 |
| 17 | 227, 391, 289, 855, 197 |
| 227, 23, 17, 855, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 227 x 23 x 17 x 855 x 197 = 508292700030
Therefore, the lowest common multiple of 454,391,578,855,197 is 508292700030.
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 391 x 578 x 855 x 197 = 17281951801020
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
391 : 1, 17, 23, 391
578 : 1, 2, 17, 34, 289, 578
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
197 : 1, 197
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 454,391,578,855,197, is 1.
Now, the common factors can be found like this.
454:2x 227
391:17x 23
578:2x 17x 17
855:3x 3x 5x 19
197:197
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 17 = 34
Therefore, the value for common factors is 34.
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 = 17281951801020/(1x34)
LCM = 17281951801020/34
LCM = 508292700030
Thus, we can understand that the LCM of 454,391,578,855,197 is 508292700030.
