Given numbers are 299,473,989,921
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 299,473,989,921 is 130254267.
Find LCM of 299,473,989,921 with Prime Factorization
| 23 | 299, 473, 989, 921 |
| 43 | 13, 473, 43, 921 |
| 13, 11, 1, 921 |
Multiply the prime numbers at the bottom and the left side.
23 x 43 x 13 x 11 x 1 x 921 = 130254267
Therefore, the lowest common multiple of 299,473,989,921 is 130254267.
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.
299 x 473 x 989 x 921 = 128821470063
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.
299 : 1, 13, 23, 299
473 : 1, 11, 43, 473
989 : 1, 23, 43, 989
921 : 1, 3, 307, 921
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 299,473,989,921, is 1.
Now, the common factors can be found like this.
299:13x 23
473:11x 43
989:23x 43
921:3x 307
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23x 43 = 989
Therefore, the value for common factors is 989.
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 = 128821470063/(1x989)
LCM = 128821470063/989
LCM = 130254267
Thus, we can understand that the LCM of 299,473,989,921 is 130254267.
