Given numbers are 267,663,481,421
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 267,663,481,421 is 919152039.
Find LCM of 267,663,481,421 with Prime Factorization
| 3 | 267, 663, 481, 421 |
| 13 | 89, 221, 481, 421 |
| 89, 17, 37, 421 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 89 x 17 x 37 x 421 = 919152039
Therefore, the lowest common multiple of 267,663,481,421 is 919152039.
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.
267 x 663 x 481 x 421 = 35846929521
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.
267 : 1, 3, 89, 267
663 : 1, 3, 13, 17, 39, 51, 221, 663
481 : 1, 13, 37, 481
421 : 1, 421
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 267,663,481,421, is 1.
Now, the common factors can be found like this.
267:3x 89
663:3x 13x 17
481:13x 37
421:421
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13 = 39
Therefore, the value for common factors is 39.
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 = 35846929521/(1x39)
LCM = 35846929521/39
LCM = 919152039
Thus, we can understand that the LCM of 267,663,481,421 is 919152039.
