Given numbers are 888,135,641,228
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 888,135,641,228 is 486672840.
Find LCM of 888,135,641,228 with Prime Factorization
| 2 | 888, 135, 641, 228 |
| 2 | 444, 135, 641, 114 |
| 3 | 222, 135, 641, 57 |
| 74, 45, 641, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 74 x 45 x 641 x 19 = 486672840
Therefore, the lowest common multiple of 888,135,641,228 is 486672840.
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.
888 x 135 x 641 x 228 = 17520222240
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.
888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888
135 : 1, 3, 5, 9, 15, 27, 45, 135
641 : 1, 641
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 888,135,641,228, is 1.
Now, the common factors can be found like this.
888:2x 2x 2x 3x 37
135:3x 3x 3x 5
641:641
228:2x 2x 3x 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 3x 3 = 36
Therefore, the value for common factors is 36.
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 = 17520222240/(1x36)
LCM = 17520222240/36
LCM = 486672840
Thus, we can understand that the LCM of 888,135,641,228 is 486672840.
