Given numbers are 743,442,235,390,836
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 743,442,235,390,836 is 96777964140.
Find LCM of 743,442,235,390,836 with Prime Factorization
| 2 | 743, 442, 235, 390, 836 |
| 5 | 743, 221, 235, 195, 418 |
| 13 | 743, 221, 47, 39, 418 |
| 743, 17, 47, 3, 418 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 743 x 17 x 47 x 3 x 418 = 96777964140
Therefore, the lowest common multiple of 743,442,235,390,836 is 96777964140.
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.
743 x 442 x 235 x 390 x 836 = 25162270676400
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.
743 : 1, 743
442 : 1, 2, 13, 17, 26, 34, 221, 442
235 : 1, 5, 47, 235
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 743,442,235,390,836, is 1.
Now, the common factors can be found like this.
743:743
442:2x 13x 17
235:5x 47
390:2x 3x 5x 13
836:2x 2x 11x 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 5x 13 = 260
Therefore, the value for common factors is 260.
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 = 25162270676400/(1x260)
LCM = 25162270676400/260
LCM = 96777964140
Thus, we can understand that the LCM of 743,442,235,390,836 is 96777964140.
