Given numbers are 668,974,969,889,748
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 668,974,969,889,748 is 3082645943916.
Find LCM of 668,974,969,889,748 with Prime Factorization
| 2 | 668, 974, 969, 889, 748 |
| 2 | 334, 487, 969, 889, 374 |
| 17 | 167, 487, 969, 889, 187 |
| 167, 487, 57, 889, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 17 x 167 x 487 x 57 x 889 x 11 = 3082645943916
Therefore, the lowest common multiple of 668,974,969,889,748 is 3082645943916.
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.
668 x 974 x 969 x 889 x 748 = 419239848372576
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.
668 : 1, 2, 4, 167, 334, 668
974 : 1, 2, 487, 974
969 : 1, 3, 17, 19, 51, 57, 323, 969
889 : 1, 7, 127, 889
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 668,974,969,889,748, is 1.
Now, the common factors can be found like this.
668:2x 2x 167
974:2x 487
969:3x 17x 19
889:7x 127
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 2x 17 = 136
Therefore, the value for common factors is 136.
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 = 419239848372576/(1x136)
LCM = 419239848372576/136
LCM = 3082645943916
Thus, we can understand that the LCM of 668,974,969,889,748 is 3082645943916.
