The LCM of 743,918,325,442 is 221674050.
Find LCM of 743,918,325,442 with Prime Factorization
| 2 | 743, 918, 325, 442 |
| 13 | 743, 459, 325, 221 |
| 17 | 743, 459, 25, 17 |
| 743, 27, 25, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 17 x 743 x 27 x 25 x 1 = 221674050
Therefore, the lowest common multiple of 743,918,325,442 is 221674050.
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 918 x 325 x 442 = 97979930100
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
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
325 : 1, 5, 13, 25, 65, 325
442 : 1, 2, 13, 17, 26, 34, 221, 442
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 743,918,325,442, is 1.
Now, the common factors can be found like this.
743:743
918:2x 3x 3x 3x 17
325:5x 5x 13
442:2x 13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 17 = 442
Therefore, the value for common factors is 442.
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 = 97979930100/(1x442)
LCM = 97979930100/442
LCM = 221674050
Thus, we can understand that the LCM of 743,918,325,442 is 221674050.
