Given numbers are 791,978,173,414,575
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 791,978,173,414,575 is 230860983150.
Find LCM of 791,978,173,414,575 with Prime Factorization
| 2 | 791, 978, 173, 414, 575 |
| 3 | 791, 489, 173, 207, 575 |
| 23 | 791, 163, 173, 69, 575 |
| 791, 163, 173, 3, 25 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 791 x 163 x 173 x 3 x 25 = 230860983150
Therefore, the lowest common multiple of 791,978,173,414,575 is 230860983150.
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.
791 x 978 x 173 x 414 x 575 = 31858815674700
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.
791 : 1, 7, 113, 791
978 : 1, 2, 3, 6, 163, 326, 489, 978
173 : 1, 173
414 : 1, 2, 3, 6, 9, 18, 23, 46, 69, 138, 207, 414
575 : 1, 5, 23, 25, 115, 575
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 791,978,173,414,575, is 1.
Now, the common factors can be found like this.
791:7x 113
978:2x 3x 163
173:173
414:2x 3x 3x 23
575:5x 5x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 23 = 138
Therefore, the value for common factors is 138.
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 = 31858815674700/(1x138)
LCM = 31858815674700/138
LCM = 230860983150
Thus, we can understand that the LCM of 791,978,173,414,575 is 230860983150.
