Given numbers are 869,242,494,845,812
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 869,242,494,845,812 is 124617432940.
Find LCM of 869,242,494,845,812 with Prime Factorization
| 2 | 869, 242, 494, 845, 812 |
| 11 | 869, 121, 247, 845, 406 |
| 13 | 79, 11, 247, 845, 406 |
| 79, 11, 19, 65, 406 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 13 x 79 x 11 x 19 x 65 x 406 = 124617432940
Therefore, the lowest common multiple of 869,242,494,845,812 is 124617432940.
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 242 x 494 x 845 x 812 = 71281171641680
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
242 : 1, 2, 11, 22, 121, 242
494 : 1, 2, 13, 19, 26, 38, 247, 494
845 : 1, 5, 13, 65, 169, 845
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 869,242,494,845,812, is 1.
Now, the common factors can be found like this.
869:11x 79
242:2x 11x 11
494:2x 13x 19
845:5x 13x 13
812:2x 2x 7x 29
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 11x 13 = 572
Therefore, the value for common factors is 572.
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 = 71281171641680/(1x572)
LCM = 71281171641680/572
LCM = 124617432940
Thus, we can understand that the LCM of 869,242,494,845,812 is 124617432940.
