Given numbers are 298,450,418,725
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 298,450,418,725 is 406390050.
Find LCM of 298,450,418,725 with Prime Factorization
| 2 | 298, 450, 418, 725 |
| 5 | 149, 225, 209, 725 |
| 5 | 149, 45, 209, 145 |
| 149, 9, 209, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 5 x 149 x 9 x 209 x 29 = 406390050
Therefore, the lowest common multiple of 298,450,418,725 is 406390050.
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.
298 x 450 x 418 x 725 = 40639005000
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.
298 : 1, 2, 149, 298
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
418 : 1, 2, 11, 19, 22, 38, 209, 418
725 : 1, 5, 25, 29, 145, 725
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 298,450,418,725, is 1.
Now, the common factors can be found like this.
298:2x 149
450:2x 3x 3x 5x 5
418:2x 11x 19
725:5x 5x 29
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 5x 5 = 100
Therefore, the value for common factors is 100.
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 = 40639005000/(1x100)
LCM = 40639005000/100
LCM = 406390050
Thus, we can understand that the LCM of 298,450,418,725 is 406390050.
