Given numbers are 362,891,338,639
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 362,891,338,639 is 3870181458.
Find LCM of 362,891,338,639 with Prime Factorization
| 2 | 362, 891, 338, 639 |
| 3 | 181, 891, 169, 639 |
| 3 | 181, 297, 169, 213 |
| 181, 99, 169, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 181 x 99 x 169 x 71 = 3870181458
Therefore, the lowest common multiple of 362,891,338,639 is 3870181458.
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.
362 x 891 x 338 x 639 = 69663266244
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.
362 : 1, 2, 181, 362
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
338 : 1, 2, 13, 26, 169, 338
639 : 1, 3, 9, 71, 213, 639
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 362,891,338,639, is 1.
Now, the common factors can be found like this.
362:2x 181
891:3x 3x 3x 3x 11
338:2x 13x 13
639:3x 3x 71
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 3 = 18
Therefore, the value for common factors is 18.
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 = 69663266244/(1x18)
LCM = 69663266244/18
LCM = 3870181458
Thus, we can understand that the LCM of 362,891,338,639 is 3870181458.
