Given numbers are 234,300,645,435,784
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 234,300,645,435,784 is 2859620400.
Find LCM of 234,300,645,435,784 with Prime Factorization
| 2 | 234, 300, 645, 435, 784 |
| 2 | 117, 150, 645, 435, 392 |
| 3 | 117, 75, 645, 435, 196 |
| 5 | 39, 25, 215, 145, 196 |
| 39, 5, 43, 29, 196 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 39 x 5 x 43 x 29 x 196 = 2859620400
Therefore, the lowest common multiple of 234,300,645,435,784 is 2859620400.
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.
234 x 300 x 645 x 435 x 784 = 15441950160000
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.
234 : 1, 2, 3, 6, 9, 13, 18, 26, 39, 78, 117, 234
300 : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, 300
645 : 1, 3, 5, 15, 43, 129, 215, 645
435 : 1, 3, 5, 15, 29, 87, 145, 435
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 234,300,645,435,784, is 1.
Now, the common factors can be found like this.
234:2x 3x 3x 13
300:2x 2x 3x 5x 5
645:3x 5x 43
435:3x 5x 29
784:2x 2x 2x 2x 7x 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 2x 3x 3x 3x 5x 5 = 5400
Therefore, the value for common factors is 5400.
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 = 15441950160000/(1x5400)
LCM = 15441950160000/5400
LCM = 2859620400
Thus, we can understand that the LCM of 234,300,645,435,784 is 2859620400.
