Given numbers are 345,445,897,454,615
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 345,445,897,454,615 is 7430057310.
Find LCM of 345,445,897,454,615 with Prime Factorization
| 3 | 345, 445, 897, 454, 615 |
| 5 | 115, 445, 299, 454, 205 |
| 23 | 23, 89, 299, 454, 41 |
| 1, 89, 13, 454, 41 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 23 x 1 x 89 x 13 x 454 x 41 = 7430057310
Therefore, the lowest common multiple of 345,445,897,454,615 is 7430057310.
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.
345 x 445 x 897 x 454 x 615 = 38450546579250
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.
345 : 1, 3, 5, 15, 23, 69, 115, 345
445 : 1, 5, 89, 445
897 : 1, 3, 13, 23, 39, 69, 299, 897
454 : 1, 2, 227, 454
615 : 1, 3, 5, 15, 41, 123, 205, 615
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 345,445,897,454,615, is 1.
Now, the common factors can be found like this.
345:3x 5x 23
445:5x 89
897:3x 13x 23
454:2x 227
615:3x 5x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 5x 23 = 5175
Therefore, the value for common factors is 5175.
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 = 38450546579250/(1x5175)
LCM = 38450546579250/5175
LCM = 7430057310
Thus, we can understand that the LCM of 345,445,897,454,615 is 7430057310.
