Given numbers are 858,490,754,849
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 858,490,754,849 is 1725193470.
Find LCM of 858,490,754,849 with Prime Factorization
2 | 858, 490, 754, 849 |
3 | 429, 245, 377, 849 |
13 | 143, 245, 377, 283 |
11, 245, 29, 283 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 11 x 245 x 29 x 283 = 1725193470
Therefore, the lowest common multiple of 858,490,754,849 is 1725193470.
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.
858 x 490 x 754 x 849 = 269130181320
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.
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
754 : 1, 2, 13, 26, 29, 58, 377, 754
849 : 1, 3, 283, 849
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 858,490,754,849, is 1.
Now, the common factors can be found like this.
858:2x 3x 11x 13
490:2x 5x 7x 7
754:2x 13x 29
849:3x 283
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 3x 13 = 156
Therefore, the value for common factors is 156.
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 = 269130181320/(1x156)
LCM = 269130181320/156
LCM = 1725193470
Thus, we can understand that the LCM of 858,490,754,849 is 1725193470.
