Given numbers are 618,800,926,724,380
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 618,800,926,724,380 is 393605930400.
Find LCM of 618,800,926,724,380 with Prime Factorization
| 2 | 618, 800, 926, 724, 380 |
| 2 | 309, 400, 463, 362, 190 |
| 5 | 309, 200, 463, 181, 95 |
| 309, 40, 463, 181, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 309 x 40 x 463 x 181 x 19 = 393605930400
Therefore, the lowest common multiple of 618,800,926,724,380 is 393605930400.
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.
618 x 800 x 926 x 724 x 380 = 125953897728000
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.
618 : 1, 2, 3, 6, 103, 206, 309, 618
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
926 : 1, 2, 463, 926
724 : 1, 2, 4, 181, 362, 724
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 618,800,926,724,380, is 2.
Now, the common factors can be found like this.
618:2x 3x 103
800:2x 2x 2x 2x 2x 5x 5
926:2x 463
724:2x 2x 181
380:2x 2x 5x 19
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 2x 2x 5 = 160
Therefore, the value for common factors is 160.
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 = 125953897728000/(2x160)
LCM = 125953897728000/320
LCM = 393605930400
Thus, we can understand that the LCM of 618,800,926,724,380 is 393605930400.
