The LCM of 318,800,492,715,905 is 134985021600.
Find LCM of 318,800,492,715,905 with Prime Factorization
| 2 | 318, 800, 492, 715, 905 |
| 2 | 159, 400, 246, 715, 905 |
| 3 | 159, 200, 123, 715, 905 |
| 5 | 53, 200, 41, 715, 905 |
| 53, 40, 41, 143, 181 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 53 x 40 x 41 x 143 x 181 = 134985021600
Therefore, the lowest common multiple of 318,800,492,715,905 is 134985021600.
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.
318 x 800 x 492 x 715 x 905 = 80991012960000
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.
318 : 1, 2, 3, 6, 53, 106, 159, 318
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
715 : 1, 5, 11, 13, 55, 65, 143, 715
905 : 1, 5, 181, 905
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 318,800,492,715,905, is 1.
Now, the common factors can be found like this.
318:2x 3x 53
800:2x 2x 2x 2x 2x 5x 5
492:2x 2x 3x 41
715:5x 11x 13
905:5x 181
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 5 = 600
Therefore, the value for common factors is 600.
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 = 80991012960000/(1x600)
LCM = 80991012960000/600
LCM = 134985021600
Thus, we can understand that the LCM of 318,800,492,715,905 is 134985021600.
