Given numbers are 931,872,420,401,313
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 931,872,420,401,313 is 1528432047240.
Find LCM of 931,872,420,401,313 with Prime Factorization
| 2 | 931, 872, 420, 401, 313 |
| 2 | 931, 436, 210, 401, 313 |
| 7 | 931, 218, 105, 401, 313 |
| 133, 218, 15, 401, 313 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 133 x 218 x 15 x 401 x 313 = 1528432047240
Therefore, the lowest common multiple of 931,872,420,401,313 is 1528432047240.
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.
931 x 872 x 420 x 401 x 313 = 42796097322720
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.
931 : 1, 7, 19, 49, 133, 931
872 : 1, 2, 4, 8, 109, 218, 436, 872
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
401 : 1, 401
313 : 1, 313
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 931,872,420,401,313, is 1.
Now, the common factors can be found like this.
931:7x 7x 19
872:2x 2x 2x 109
420:2x 2x 3x 5x 7
401:401
313:313
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 7 = 28
Therefore, the value for common factors is 28.
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 = 42796097322720/(1x28)
LCM = 42796097322720/28
LCM = 1528432047240
Thus, we can understand that the LCM of 931,872,420,401,313 is 1528432047240.
