Given numbers are 387,803,753,803
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 387,803,753,803 is 78001011.
Find LCM of 387,803,753,803 with Prime Factorization
| 3 | 387, 803, 753, 803 |
| 11 | 129, 803, 251, 803 |
| 73 | 129, 73, 251, 73 |
| 129, 1, 251, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 73 x 129 x 1 x 251 x 1 = 78001011
Therefore, the lowest common multiple of 387,803,753,803 is 78001011.
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.
387 x 803 x 753 x 803 = 187904435499
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.
387 : 1, 3, 9, 43, 129, 387
803 : 1, 11, 73, 803
753 : 1, 3, 251, 753
803 : 1, 11, 73, 803
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 387,803,753,803, is 1.
Now, the common factors can be found like this.
387:3x 3x 43
803:11x 73
753:3x 251
803:11x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 73 = 2409
Therefore, the value for common factors is 2409.
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 = 187904435499/(1x2409)
LCM = 187904435499/2409
LCM = 78001011
Thus, we can understand that the LCM of 387,803,753,803 is 78001011.
