Given numbers are 787,398,150,831,210
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 787,398,150,831,210 is 45550891050.
Find LCM of 787,398,150,831,210 with Prime Factorization
| 2 | 787, 398, 150, 831, 210 |
| 3 | 787, 199, 75, 831, 105 |
| 5 | 787, 199, 25, 277, 35 |
| 787, 199, 5, 277, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 787 x 199 x 5 x 277 x 7 = 45550891050
Therefore, the lowest common multiple of 787,398,150,831,210 is 45550891050.
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.
787 x 398 x 150 x 831 x 210 = 8199160389000
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.
787 : 1, 787
398 : 1, 2, 199, 398
150 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 150
831 : 1, 3, 277, 831
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 787,398,150,831,210, is 1.
Now, the common factors can be found like this.
787:787
398:2x 199
150:2x 3x 5x 5
831:3x 277
210:2x 3x 5x 7
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 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 8199160389000/(1x180)
LCM = 8199160389000/180
LCM = 45550891050
Thus, we can understand that the LCM of 787,398,150,831,210 is 45550891050.
