Given numbers are 591,447,842,692,438
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 591,447,842,692,438 is 1872771534924.
Find LCM of 591,447,842,692,438 with Prime Factorization
| 2 | 591, 447, 842, 692, 438 |
| 3 | 591, 447, 421, 346, 219 |
| 197, 149, 421, 346, 73 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 197 x 149 x 421 x 346 x 73 = 1872771534924
Therefore, the lowest common multiple of 591,447,842,692,438 is 1872771534924.
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.
591 x 447 x 842 x 692 x 438 = 67419775257264
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.
591 : 1, 3, 197, 591
447 : 1, 3, 149, 447
842 : 1, 2, 421, 842
692 : 1, 2, 4, 173, 346, 692
438 : 1, 2, 3, 6, 73, 146, 219, 438
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 591,447,842,692,438, is 1.
Now, the common factors can be found like this.
591:3x 197
447:3x 149
842:2x 421
692:2x 2x 173
438:2x 3x 73
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 3 = 36
Therefore, the value for common factors is 36.
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 = 67419775257264/(1x36)
LCM = 67419775257264/36
LCM = 1872771534924
Thus, we can understand that the LCM of 591,447,842,692,438 is 1872771534924.
