Given numbers are 251,748,880,809
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 251,748,880,809 is 3037762640.
Find LCM of 251,748,880,809 with Prime Factorization
| 2 | 251, 748, 880, 809 |
| 2 | 251, 374, 440, 809 |
| 11 | 251, 187, 220, 809 |
| 251, 17, 20, 809 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 251 x 17 x 20 x 809 = 3037762640
Therefore, the lowest common multiple of 251,748,880,809 is 3037762640.
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.
251 x 748 x 880 x 809 = 133661556160
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.
251 : 1, 251
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
809 : 1, 809
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 251,748,880,809, is 1.
Now, the common factors can be found like this.
251:251
748:2x 2x 11x 17
880:2x 2x 2x 2x 5x 11
809:809
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 11 = 44
Therefore, the value for common factors is 44.
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 = 133661556160/(1x44)
LCM = 133661556160/44
LCM = 3037762640
Thus, we can understand that the LCM of 251,748,880,809 is 3037762640.
