Given numbers are 498,743,387,645
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 498,743,387,645 is 238659030.
Find LCM of 498,743,387,645 with Prime Factorization
| 3 | 498, 743, 387, 645 |
| 43 | 166, 743, 129, 215 |
| 166, 743, 3, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 43 x 166 x 743 x 3 x 5 = 238659030
Therefore, the lowest common multiple of 498,743,387,645 is 238659030.
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.
498 x 743 x 387 x 645 = 92361044610
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.
498 : 1, 2, 3, 6, 83, 166, 249, 498
743 : 1, 743
387 : 1, 3, 9, 43, 129, 387
645 : 1, 3, 5, 15, 43, 129, 215, 645
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 498,743,387,645, is 1.
Now, the common factors can be found like this.
498:2x 3x 83
743:743
387:3x 3x 43
645:3x 5x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 43 = 387
Therefore, the value for common factors is 387.
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 = 92361044610/(1x387)
LCM = 92361044610/387
LCM = 238659030
Thus, we can understand that the LCM of 498,743,387,645 is 238659030.
