Given numbers are 393,284,493,928
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 393,284,493,928 is 440197728.
Find LCM of 393,284,493,928 with Prime Factorization
| 2 | 393, 284, 493, 928 |
| 2 | 393, 142, 493, 464 |
| 29 | 393, 71, 493, 232 |
| 393, 71, 17, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 29 x 393 x 71 x 17 x 8 = 440197728
Therefore, the lowest common multiple of 393,284,493,928 is 440197728.
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.
393 x 284 x 493 x 928 = 51062936448
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.
393 : 1, 3, 131, 393
284 : 1, 2, 4, 71, 142, 284
493 : 1, 17, 29, 493
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 393,284,493,928, is 1.
Now, the common factors can be found like this.
393:3x 131
284:2x 2x 71
493:17x 29
928:2x 2x 2x 2x 2x 29
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 29 = 116
Therefore, the value for common factors is 116.
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 = 51062936448/(1x116)
LCM = 51062936448/116
LCM = 440197728
Thus, we can understand that the LCM of 393,284,493,928 is 440197728.
