Given numbers are 906,408,403,419,749
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 906,408,403,419,749 is 7791803599944.
Find LCM of 906,408,403,419,749 with Prime Factorization
| 2 | 906, 408, 403, 419, 749 |
| 3 | 453, 204, 403, 419, 749 |
| 151, 68, 403, 419, 749 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 151 x 68 x 403 x 419 x 749 = 7791803599944
Therefore, the lowest common multiple of 906,408,403,419,749 is 7791803599944.
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.
906 x 408 x 403 x 419 x 749 = 46750821599664
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.
906 : 1, 2, 3, 6, 151, 302, 453, 906
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
403 : 1, 13, 31, 403
419 : 1, 419
749 : 1, 7, 107, 749
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 906,408,403,419,749, is 1.
Now, the common factors can be found like this.
906:2x 3x 151
408:2x 2x 2x 3x 17
403:13x 31
419:419
749:7x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 46750821599664/(1x6)
LCM = 46750821599664/6
LCM = 7791803599944
Thus, we can understand that the LCM of 906,408,403,419,749 is 7791803599944.
