Given numbers are 488,869,948,641
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 488,869,948,641 is 815490456.
Find LCM of 488,869,948,641 with Prime Factorization
| 2 | 488, 869, 948, 641 |
| 2 | 244, 869, 474, 641 |
| 79 | 122, 869, 237, 641 |
| 122, 11, 3, 641 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 79 x 122 x 11 x 3 x 641 = 815490456
Therefore, the lowest common multiple of 488,869,948,641 is 815490456.
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.
488 x 869 x 948 x 641 = 257694984096
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.
488 : 1, 2, 4, 8, 61, 122, 244, 488
869 : 1, 11, 79, 869
948 : 1, 2, 3, 4, 6, 12, 79, 158, 237, 316, 474, 948
641 : 1, 641
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 488,869,948,641, is 1.
Now, the common factors can be found like this.
488:2x 2x 2x 61
869:11x 79
948:2x 2x 3x 79
641:641
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 79 = 316
Therefore, the value for common factors is 316.
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 = 257694984096/(1x316)
LCM = 257694984096/316
LCM = 815490456
Thus, we can understand that the LCM of 488,869,948,641 is 815490456.
