Given numbers are 853,642,494
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 853,642,494 is 135263622.
Find LCM of 853,642,494 with Prime Factorization
| 2 | 853, 642, 494 |
| 853, 321, 247 |
Multiply the prime numbers at the bottom and the left side.
2 x 853 x 321 x 247 = 135263622
Therefore, the lowest common multiple of 853,642,494 is 135263622.
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.
853 x 642 x 494 = 270527244
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.
853 : 1, 853
642 : 1, 2, 3, 6, 107, 214, 321, 642
494 : 1, 2, 13, 19, 26, 38, 247, 494
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 853,642,494, is 1.
Now, the common factors can be found like this.
853:853
642:2x 3x 107
494:2x 13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 270527244/(1x2)
LCM = 270527244/2
LCM = 135263622
Thus, we can understand that the LCM of 853,642,494 is 135263622.
