Given numbers are 976,138,667,667
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 976,138,667,667 is 1952976.
Find LCM of 976,138,667,667 with Prime Factorization
| 2 | 976, 138, 667, 667 |
| 23 | 488, 69, 667, 667 |
| 29 | 488, 3, 29, 29 |
| 488, 3, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 23 x 29 x 488 x 3 x 1 x 1 = 1952976
Therefore, the lowest common multiple of 976,138,667,667 is 1952976.
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.
976 x 138 x 667 x 667 = 59921209632
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.
976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976
138 : 1, 2, 3, 6, 23, 46, 69, 138
667 : 1, 23, 29, 667
667 : 1, 23, 29, 667
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 976,138,667,667, is 1.
Now, the common factors can be found like this.
976:2x 2x 2x 2x 61
138:2x 3x 23
667:23x 29
667:23x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 23x 23x 29 = 30682
Therefore, the value for common factors is 30682.
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 = 59921209632/(1x30682)
LCM = 59921209632/30682
LCM = 1952976
Thus, we can understand that the LCM of 976,138,667,667 is 1952976.
