Given numbers are 668,153,949,939
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 668,153,949,939 is 30358369548.
Find LCM of 668,153,949,939 with Prime Factorization
| 3 | 668, 153, 949, 939 |
| 668, 51, 949, 313 |
Multiply the prime numbers at the bottom and the left side.
3 x 668 x 51 x 949 x 313 = 30358369548
Therefore, the lowest common multiple of 668,153,949,939 is 30358369548.
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 153 x 949 x 939 = 91075108644
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
153 : 1, 3, 9, 17, 51, 153
949 : 1, 13, 73, 949
939 : 1, 3, 313, 939
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,153,949,939, is 1.
Now, the common factors can be found like this.
668:2x 2x 167
153:3x 3x 17
949:13x 73
939:3x 313
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 = 91075108644/(1x3)
LCM = 91075108644/3
LCM = 30358369548
Thus, we can understand that the LCM of 668,153,949,939 is 30358369548.
