Given numbers are 980,800,436,320
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 980,800,436,320 is 8545600.
Find LCM of 980,800,436,320 with Prime Factorization
| 2 | 980, 800, 436, 320 |
| 2 | 490, 400, 218, 160 |
| 2 | 245, 200, 109, 80 |
| 2 | 245, 100, 109, 40 |
| 2 | 245, 50, 109, 20 |
| 5 | 245, 25, 109, 10 |
| 49, 5, 109, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 5 x 49 x 5 x 109 x 2 = 8545600
Therefore, the lowest common multiple of 980,800,436,320 is 8545600.
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.
980 x 800 x 436 x 320 = 109383680000
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.
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
436 : 1, 2, 4, 109, 218, 436
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 980,800,436,320, is 4.
Now, the common factors can be found like this.
980:2x 2x 5x 7x 7
800:2x 2x 2x 2x 2x 5x 5
436:2x 2x 109
320:2x 2x 2x 2x 2x 2x 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 2x 2x 2x 2x 2x 2x 5x 5 = 3200
Therefore, the value for common factors is 3200.
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 = 109383680000/(4x3200)
LCM = 109383680000/12800
LCM = 8545600
Thus, we can understand that the LCM of 980,800,436,320 is 8545600.
