Given numbers are 667,672,455,667,971
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 667,672,455,667,971 is 28289657760.
Find LCM of 667,672,455,667,971 with Prime Factorization
| 7 | 667, 672, 455, 667, 971 |
| 23 | 667, 96, 65, 667, 971 |
| 29 | 29, 96, 65, 29, 971 |
| 1, 96, 65, 1, 971 |
Multiply the prime numbers at the bottom and the left side.
7 x 23 x 29 x 1 x 96 x 65 x 1 x 971 = 28289657760
Therefore, the lowest common multiple of 667,672,455,667,971 is 28289657760.
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.
667 x 672 x 455 x 667 x 971 = 132084412081440
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.
667 : 1, 23, 29, 667
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
455 : 1, 5, 7, 13, 35, 65, 91, 455
667 : 1, 23, 29, 667
971 : 1, 971
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 667,672,455,667,971, is 1.
Now, the common factors can be found like this.
667:23x 29
672:2x 2x 2x 2x 2x 3x 7
455:5x 7x 13
667:23x 29
971:971
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 23x 29 = 4669
Therefore, the value for common factors is 4669.
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 = 132084412081440/(1x4669)
LCM = 132084412081440/4669
LCM = 28289657760
Thus, we can understand that the LCM of 667,672,455,667,971 is 28289657760.
