The LCM of 363,784,644,581 is 543286128.
Find LCM of 363,784,644,581 with Prime Factorization
| 2 | 363, 784, 644, 581 |
| 2 | 363, 392, 322, 581 |
| 7 | 363, 196, 161, 581 |
| 363, 28, 23, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 363 x 28 x 23 x 83 = 543286128
Therefore, the lowest common multiple of 363,784,644,581 is 543286128.
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.
363 x 784 x 644 x 581 = 106484081088
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.
363 : 1, 3, 11, 33, 121, 363
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
581 : 1, 7, 83, 581
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 363,784,644,581, is 1.
Now, the common factors can be found like this.
363:3x 11x 11
784:2x 2x 2x 2x 7x 7
644:2x 2x 7x 23
581:7x 83
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 7x 7 = 196
Therefore, the value for common factors is 196.
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 = 106484081088/(1x196)
LCM = 106484081088/196
LCM = 543286128
Thus, we can understand that the LCM of 363,784,644,581 is 543286128.
