Given numbers are 961,558,930,901
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 961,558,930,901 is 77927490.
Find LCM of 961,558,930,901 with Prime Factorization
| 2 | 961, 558, 930, 901 |
| 3 | 961, 279, 465, 901 |
| 31 | 961, 93, 155, 901 |
| 31, 3, 5, 901 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 31 x 31 x 3 x 5 x 901 = 77927490
Therefore, the lowest common multiple of 961,558,930,901 is 77927490.
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.
961 x 558 x 930 x 901 = 449329907340
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.
961 : 1, 31, 961
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
901 : 1, 17, 53, 901
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 961,558,930,901, is 1.
Now, the common factors can be found like this.
961:31x 31
558:2x 3x 3x 31
930:2x 3x 5x 31
901:17x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 31x 31 = 5766
Therefore, the value for common factors is 5766.
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 = 449329907340/(1x5766)
LCM = 449329907340/5766
LCM = 77927490
Thus, we can understand that the LCM of 961,558,930,901 is 77927490.
