Given numbers are 705,182,815,458
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 705,182,815,458 is 4789427370.
Find LCM of 705,182,815,458 with Prime Factorization
| 2 | 705, 182, 815, 458 |
| 5 | 705, 91, 815, 229 |
| 141, 91, 163, 229 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 141 x 91 x 163 x 229 = 4789427370
Therefore, the lowest common multiple of 705,182,815,458 is 4789427370.
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.
705 x 182 x 815 x 458 = 47894273700
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.
705 : 1, 3, 5, 15, 47, 141, 235, 705
182 : 1, 2, 7, 13, 14, 26, 91, 182
815 : 1, 5, 163, 815
458 : 1, 2, 229, 458
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 705,182,815,458, is 1.
Now, the common factors can be found like this.
705:3x 5x 47
182:2x 7x 13
815:5x 163
458:2x 229
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 47894273700/(1x10)
LCM = 47894273700/10
LCM = 4789427370
Thus, we can understand that the LCM of 705,182,815,458 is 4789427370.
