Given numbers are 331,390,615,250
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 331,390,615,250 is 132317250.
Find LCM of 331,390,615,250 with Prime Factorization
| 2 | 331, 390, 615, 250 |
| 3 | 331, 195, 615, 125 |
| 5 | 331, 65, 205, 125 |
| 331, 13, 41, 25 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 331 x 13 x 41 x 25 = 132317250
Therefore, the lowest common multiple of 331,390,615,250 is 132317250.
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.
331 x 390 x 615 x 250 = 19847587500
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.
331 : 1, 331
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
615 : 1, 3, 5, 15, 41, 123, 205, 615
250 : 1, 2, 5, 10, 25, 50, 125, 250
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 331,390,615,250, is 1.
Now, the common factors can be found like this.
331:331
390:2x 3x 5x 13
615:3x 5x 41
250:2x 5x 5x 5
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 5x 5 = 150
Therefore, the value for common factors is 150.
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 = 19847587500/(1x150)
LCM = 19847587500/150
LCM = 132317250
Thus, we can understand that the LCM of 331,390,615,250 is 132317250.
