Given numbers are 523,856,321
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 523,856,321 is 1343064.
Find LCM of 523,856,321 with Prime Factorization
| 107 | 523, 856, 321 |
| 523, 8, 3 |
Multiply the prime numbers at the bottom and the left side.
107 x 523 x 8 x 3 = 1343064
Therefore, the lowest common multiple of 523,856,321 is 1343064.
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.
523 x 856 x 321 = 143707848
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.
523 : 1, 523
856 : 1, 2, 4, 8, 107, 214, 428, 856
321 : 1, 3, 107, 321
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 523,856,321, is 1.
Now, the common factors can be found like this.
523:523
856:2x 2x 2x 107
321:3x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
107 = 107
Therefore, the value for common factors is 107.
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 = 143707848/(1x107)
LCM = 143707848/107
LCM = 1343064
Thus, we can understand that the LCM of 523,856,321 is 1343064.
