Given numbers are 970,110,615,720,398
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 970,110,615,720,398 is 6268070160.
Find LCM of 970,110,615,720,398 with Prime Factorization
| 2 | 970, 110, 615, 720, 398 |
| 3 | 485, 55, 615, 360, 199 |
| 5 | 485, 55, 205, 120, 199 |
| 97, 11, 41, 24, 199 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 97 x 11 x 41 x 24 x 199 = 6268070160
Therefore, the lowest common multiple of 970,110,615,720,398 is 6268070160.
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.
970 x 110 x 615 x 720 x 398 = 18804210480000
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.
970 : 1, 2, 5, 10, 97, 194, 485, 970
110 : 1, 2, 5, 10, 11, 22, 55, 110
615 : 1, 3, 5, 15, 41, 123, 205, 615
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
398 : 1, 2, 199, 398
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 970,110,615,720,398, is 1.
Now, the common factors can be found like this.
970:2x 5x 97
110:2x 5x 11
615:3x 5x 41
720:2x 2x 2x 2x 3x 3x 5
398:2x 199
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 2x 3x 5x 5x 5 = 3000
Therefore, the value for common factors is 3000.
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 = 18804210480000/(1x3000)
LCM = 18804210480000/3000
LCM = 6268070160
Thus, we can understand that the LCM of 970,110,615,720,398 is 6268070160.
