Given numbers are 801,387,144,874
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 801,387,144,874 is 240825456.
Find LCM of 801,387,144,874 with Prime Factorization
| 2 | 801, 387, 144, 874 |
| 3 | 801, 387, 72, 437 |
| 3 | 267, 129, 24, 437 |
| 89, 43, 8, 437 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 89 x 43 x 8 x 437 = 240825456
Therefore, the lowest common multiple of 801,387,144,874 is 240825456.
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.
801 x 387 x 144 x 874 = 39013723872
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.
801 : 1, 3, 9, 89, 267, 801
387 : 1, 3, 9, 43, 129, 387
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
874 : 1, 2, 19, 23, 38, 46, 437, 874
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 801,387,144,874, is 1.
Now, the common factors can be found like this.
801:3x 3x 89
387:3x 3x 43
144:2x 2x 2x 2x 3x 3
874:2x 19x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 3 = 162
Therefore, the value for common factors is 162.
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 = 39013723872/(1x162)
LCM = 39013723872/162
LCM = 240825456
Thus, we can understand that the LCM of 801,387,144,874 is 240825456.
