Given numbers are 949,561,286,165
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 949,561,286,165 is 5323890.
Find LCM of 949,561,286,165 with Prime Factorization
| 3 | 949, 561, 286, 165 |
| 11 | 949, 187, 286, 55 |
| 13 | 949, 17, 26, 5 |
| 73, 17, 2, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 13 x 73 x 17 x 2 x 5 = 5323890
Therefore, the lowest common multiple of 949,561,286,165 is 5323890.
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.
949 x 561 x 286 x 165 = 25123436910
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.
949 : 1, 13, 73, 949
561 : 1, 3, 11, 17, 33, 51, 187, 561
286 : 1, 2, 11, 13, 22, 26, 143, 286
165 : 1, 3, 5, 11, 15, 33, 55, 165
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 949,561,286,165, is 1.
Now, the common factors can be found like this.
949:13x 73
561:3x 11x 17
286:2x 11x 13
165:3x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 11x 13 = 4719
Therefore, the value for common factors is 4719.
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 = 25123436910/(1x4719)
LCM = 25123436910/4719
LCM = 5323890
Thus, we can understand that the LCM of 949,561,286,165 is 5323890.
