Given numbers are 754,128,794,280
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 754,128,794,280 is 670517120.
Find LCM of 754,128,794,280 with Prime Factorization
| 2 | 754, 128, 794, 280 |
| 2 | 377, 64, 397, 140 |
| 2 | 377, 32, 397, 70 |
| 377, 16, 397, 35 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 377 x 16 x 397 x 35 = 670517120
Therefore, the lowest common multiple of 754,128,794,280 is 670517120.
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.
754 x 128 x 794 x 280 = 21456547840
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.
754 : 1, 2, 13, 26, 29, 58, 377, 754
128 : 1, 2, 4, 8, 16, 32, 64, 128
794 : 1, 2, 397, 794
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 754,128,794,280, is 2.
Now, the common factors can be found like this.
754:2x 13x 29
128:2x 2x 2x 2x 2x 2x 2
794:2x 397
280:2x 2x 2x 5x 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 2 = 16
Therefore, the value for common factors is 16.
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 = 21456547840/(2x16)
LCM = 21456547840/32
LCM = 670517120
Thus, we can understand that the LCM of 754,128,794,280 is 670517120.
