Given numbers are 749,585,471,961
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 749,585,471,961 is 66109020705.
Find LCM of 749,585,471,961 with Prime Factorization
| 3 | 749, 585, 471, 961 |
| 749, 195, 157, 961 |
Multiply the prime numbers at the bottom and the left side.
3 x 749 x 195 x 157 x 961 = 66109020705
Therefore, the lowest common multiple of 749,585,471,961 is 66109020705.
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.
749 x 585 x 471 x 961 = 198327062115
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.
749 : 1, 7, 107, 749
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
471 : 1, 3, 157, 471
961 : 1, 31, 961
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,585,471,961, is 1.
Now, the common factors can be found like this.
749:7x 107
585:3x 3x 5x 13
471:3x 157
961:31x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 198327062115/(1x3)
LCM = 198327062115/3
LCM = 66109020705
Thus, we can understand that the LCM of 749,585,471,961 is 66109020705.
