Given numbers are 931,100,380,442,679
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 931,100,380,442,679 is 1995784700.
Find LCM of 931,100,380,442,679 with Prime Factorization
| 2 | 931, 100, 380, 442, 679 |
| 2 | 931, 50, 190, 221, 679 |
| 5 | 931, 25, 95, 221, 679 |
| 7 | 931, 5, 19, 221, 679 |
| 19 | 133, 5, 19, 221, 97 |
| 7, 5, 1, 221, 97 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 19 x 7 x 5 x 1 x 221 x 97 = 1995784700
Therefore, the lowest common multiple of 931,100,380,442,679 is 1995784700.
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 100 x 380 x 442 x 679 = 10617574604000
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
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
442 : 1, 2, 13, 17, 26, 34, 221, 442
679 : 1, 7, 97, 679
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 931,100,380,442,679, is 1.
Now, the common factors can be found like this.
931:7x 7x 19
100:2x 2x 5x 5
380:2x 2x 5x 19
442:2x 13x 17
679:7x 97
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 2x 5x 7x 19 = 5320
Therefore, the value for common factors is 5320.
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 = 10617574604000/(1x5320)
LCM = 10617574604000/5320
LCM = 1995784700
Thus, we can understand that the LCM of 931,100,380,442,679 is 1995784700.
