Given numbers are 921,389,309,695,328
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 921,389,309,695,328 is 8412113127720.
Find LCM of 921,389,309,695,328 with Prime Factorization
| 3 | 921, 389, 309, 695, 328 |
| 307, 389, 103, 695, 328 |
Multiply the prime numbers at the bottom and the left side.
3 x 307 x 389 x 103 x 695 x 328 = 8412113127720
Therefore, the lowest common multiple of 921,389,309,695,328 is 8412113127720.
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 389 x 309 x 695 x 328 = 25236339383160
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
389 : 1, 389
309 : 1, 3, 103, 309
695 : 1, 5, 139, 695
328 : 1, 2, 4, 8, 41, 82, 164, 328
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,389,309,695,328, is 1.
Now, the common factors can be found like this.
921:3x 307
389:389
309:3x 103
695:5x 139
328:2x 2x 2x 41
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 = 25236339383160/(1x3)
LCM = 25236339383160/3
LCM = 8412113127720
Thus, we can understand that the LCM of 921,389,309,695,328 is 8412113127720.
