Given numbers are 245,299,230,920,991
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 245,299,230,920,991 is 580765640.
Find LCM of 245,299,230,920,991 with Prime Factorization
| 2 | 245, 299, 230, 920, 991 |
| 5 | 245, 299, 115, 460, 991 |
| 23 | 49, 299, 23, 92, 991 |
| 49, 13, 1, 4, 991 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 23 x 49 x 13 x 1 x 4 x 991 = 580765640
Therefore, the lowest common multiple of 245,299,230,920,991 is 580765640.
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.
245 x 299 x 230 x 920 x 991 = 15361251178000
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.
245 : 1, 5, 7, 35, 49, 245
299 : 1, 13, 23, 299
230 : 1, 2, 5, 10, 23, 46, 115, 230
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
991 : 1, 991
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 245,299,230,920,991, is 1.
Now, the common factors can be found like this.
245:5x 7x 7
299:13x 23
230:2x 5x 23
920:2x 2x 2x 5x 23
991:991
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 23x 23 = 26450
Therefore, the value for common factors is 26450.
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 = 15361251178000/(1x26450)
LCM = 15361251178000/26450
LCM = 580765640
Thus, we can understand that the LCM of 245,299,230,920,991 is 580765640.
