Given numbers are 869,308,321,817,488
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 869,308,321,817,488 is 778510953528.
Find LCM of 869,308,321,817,488 with Prime Factorization
| 2 | 869, 308, 321, 817, 488 |
| 2 | 869, 154, 321, 817, 244 |
| 11 | 869, 77, 321, 817, 122 |
| 79, 7, 321, 817, 122 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 79 x 7 x 321 x 817 x 122 = 778510953528
Therefore, the lowest common multiple of 869,308,321,817,488 is 778510953528.
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.
869 x 308 x 321 x 817 x 488 = 34254481955232
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.
869 : 1, 11, 79, 869
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
321 : 1, 3, 107, 321
817 : 1, 19, 43, 817
488 : 1, 2, 4, 8, 61, 122, 244, 488
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 869,308,321,817,488, is 1.
Now, the common factors can be found like this.
869:11x 79
308:2x 2x 7x 11
321:3x 107
817:19x 43
488:2x 2x 2x 61
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 11 = 44
Therefore, the value for common factors is 44.
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 = 34254481955232/(1x44)
LCM = 34254481955232/44
LCM = 778510953528
Thus, we can understand that the LCM of 869,308,321,817,488 is 778510953528.
