Given numbers are 115,145,371,639
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 115,145,371,639 is 790625115.
Find LCM of 115,145,371,639 with Prime Factorization
| 5 | 115, 145, 371, 639 |
| 23, 29, 371, 639 |
Multiply the prime numbers at the bottom and the left side.
5 x 23 x 29 x 371 x 639 = 790625115
Therefore, the lowest common multiple of 115,145,371,639 is 790625115.
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.
115 x 145 x 371 x 639 = 3953125575
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.
115 : 1, 5, 23, 115
145 : 1, 5, 29, 145
371 : 1, 7, 53, 371
639 : 1, 3, 9, 71, 213, 639
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 115,145,371,639, is 1.
Now, the common factors can be found like this.
115:5x 23
145:5x 29
371:7x 53
639:3x 3x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
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 = 3953125575/(1x5)
LCM = 3953125575/5
LCM = 790625115
Thus, we can understand that the LCM of 115,145,371,639 is 790625115.
