Given numbers are 438,142,610
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 438,142,610 is 9484890.
Find LCM of 438,142,610 with Prime Factorization
| 2 | 438, 142, 610 |
| 219, 71, 305 |
Multiply the prime numbers at the bottom and the left side.
2 x 219 x 71 x 305 = 9484890
Therefore, the lowest common multiple of 438,142,610 is 9484890.
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.
438 x 142 x 610 = 37939560
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.
438 : 1, 2, 3, 6, 73, 146, 219, 438
142 : 1, 2, 71, 142
610 : 1, 2, 5, 10, 61, 122, 305, 610
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 438,142,610, is 2.
Now, the common factors can be found like this.
438:2x 3x 73
142:2x 71
610:2x 5x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 37939560/(2x2)
LCM = 37939560/4
LCM = 9484890
Thus, we can understand that the LCM of 438,142,610 is 9484890.
