Given numbers are 824,757,578,309
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 824,757,578,309 is 540806856.
Find LCM of 824,757,578,309 with Prime Factorization
| 2 | 824, 757, 578, 309 |
| 103 | 412, 757, 289, 309 |
| 4, 757, 289, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 103 x 4 x 757 x 289 x 3 = 540806856
Therefore, the lowest common multiple of 824,757,578,309 is 540806856.
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.
824 x 757 x 578 x 309 = 111406212336
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.
824 : 1, 2, 4, 8, 103, 206, 412, 824
757 : 1, 757
578 : 1, 2, 17, 34, 289, 578
309 : 1, 3, 103, 309
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 824,757,578,309, is 1.
Now, the common factors can be found like this.
824:2x 2x 2x 103
757:757
578:2x 17x 17
309:3x 103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 103 = 206
Therefore, the value for common factors is 206.
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 = 111406212336/(1x206)
LCM = 111406212336/206
LCM = 540806856
Thus, we can understand that the LCM of 824,757,578,309 is 540806856.
