Given numbers are 909,671,771,160,748
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 909,671,771,160,748 is 426371758560.
Find LCM of 909,671,771,160,748 with Prime Factorization
| 2 | 909, 671, 771, 160, 748 |
| 2 | 909, 671, 771, 80, 374 |
| 3 | 909, 671, 771, 40, 187 |
| 11 | 303, 671, 257, 40, 187 |
| 303, 61, 257, 40, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 303 x 61 x 257 x 40 x 17 = 426371758560
Therefore, the lowest common multiple of 909,671,771,160,748 is 426371758560.
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.
909 x 671 x 771 x 160 x 748 = 56281072129920
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.
909 : 1, 3, 9, 101, 303, 909
671 : 1, 11, 61, 671
771 : 1, 3, 257, 771
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 909,671,771,160,748, is 1.
Now, the common factors can be found like this.
909:3x 3x 101
671:11x 61
771:3x 257
160:2x 2x 2x 2x 2x 5
748:2x 2x 11x 17
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 3x 11 = 132
Therefore, the value for common factors is 132.
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 = 56281072129920/(1x132)
LCM = 56281072129920/132
LCM = 426371758560
Thus, we can understand that the LCM of 909,671,771,160,748 is 426371758560.
