Given numbers are 673,391,748,897
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 673,391,748,897 is 451553388.
Find LCM of 673,391,748,897 with Prime Factorization
| 17 | 673, 391, 748, 897 |
| 23 | 673, 23, 44, 897 |
| 673, 1, 44, 39 |
Multiply the prime numbers at the bottom and the left side.
17 x 23 x 673 x 1 x 44 x 39 = 451553388
Therefore, the lowest common multiple of 673,391,748,897 is 451553388.
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.
673 x 391 x 748 x 897 = 176557374708
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.
673 : 1, 673
391 : 1, 17, 23, 391
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
897 : 1, 3, 13, 23, 39, 69, 299, 897
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 673,391,748,897, is 1.
Now, the common factors can be found like this.
673:673
391:17x 23
748:2x 2x 11x 17
897:3x 13x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17x 23 = 391
Therefore, the value for common factors is 391.
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 = 176557374708/(1x391)
LCM = 176557374708/391
LCM = 451553388
Thus, we can understand that the LCM of 673,391,748,897 is 451553388.
