Given numbers are 931,490,358,494
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 931,490,358,494 is 21664370.
Find LCM of 931,490,358,494 with Prime Factorization
| 2 | 931, 490, 358, 494 |
| 7 | 931, 245, 179, 247 |
| 7 | 133, 35, 179, 247 |
| 19 | 19, 5, 179, 247 |
| 1, 5, 179, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 7 x 19 x 1 x 5 x 179 x 13 = 21664370
Therefore, the lowest common multiple of 931,490,358,494 is 21664370.
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 490 x 358 x 494 = 80678113880
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
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
358 : 1, 2, 179, 358
494 : 1, 2, 13, 19, 26, 38, 247, 494
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 931,490,358,494, is 1.
Now, the common factors can be found like this.
931:7x 7x 19
490:2x 5x 7x 7
358:2x 179
494:2x 13x 19
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 7x 7x 19 = 3724
Therefore, the value for common factors is 3724.
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 = 80678113880/(1x3724)
LCM = 80678113880/3724
LCM = 21664370
Thus, we can understand that the LCM of 931,490,358,494 is 21664370.
