Given numbers are 921,856,454,939,749
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 921,856,454,939,749 is 392104322232.
Find LCM of 921,856,454,939,749 with Prime Factorization
2 | 921, 856, 454, 939, 749 |
3 | 921, 428, 227, 939, 749 |
107 | 307, 428, 227, 313, 749 |
307, 4, 227, 313, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 107 x 307 x 4 x 227 x 313 x 7 = 392104322232
Therefore, the lowest common multiple of 921,856,454,939,749 is 392104322232.
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.
921 x 856 x 454 x 939 x 749 = 251730974872944
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.
921 : 1, 3, 307, 921
856 : 1, 2, 4, 8, 107, 214, 428, 856
454 : 1, 2, 227, 454
939 : 1, 3, 313, 939
749 : 1, 7, 107, 749
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,856,454,939,749, is 1.
Now, the common factors can be found like this.
921:3x 307
856:2x 2x 2x 107
454:2x 227
939:3x 313
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 3x 107 = 642
Therefore, the value for common factors is 642.
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 = 251730974872944/(1x642)
LCM = 251730974872944/642
LCM = 392104322232
Thus, we can understand that the LCM of 921,856,454,939,749 is 392104322232.
