Given numbers are 821,688,131,559
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 821,688,131,559 is 961936144.
Find LCM of 821,688,131,559 with Prime Factorization
| 43 | 821, 688, 131, 559 |
| 821, 16, 131, 13 |
Multiply the prime numbers at the bottom and the left side.
43 x 821 x 16 x 131 x 13 = 961936144
Therefore, the lowest common multiple of 821,688,131,559 is 961936144.
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.
821 x 688 x 131 x 559 = 41363254192
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.
821 : 1, 821
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
131 : 1, 131
559 : 1, 13, 43, 559
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,688,131,559, is 1.
Now, the common factors can be found like this.
821:821
688:2x 2x 2x 2x 43
131:131
559:13x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
43 = 43
Therefore, the value for common factors is 43.
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 = 41363254192/(1x43)
LCM = 41363254192/43
LCM = 961936144
Thus, we can understand that the LCM of 821,688,131,559 is 961936144.
