Given numbers are 517,979,438
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 517,979,438 is 20153694.
Find LCM of 517,979,438 with Prime Factorization
| 11 | 517, 979, 438 |
| 47, 89, 438 |
Multiply the prime numbers at the bottom and the left side.
11 x 47 x 89 x 438 = 20153694
Therefore, the lowest common multiple of 517,979,438 is 20153694.
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.
517 x 979 x 438 = 221690634
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.
517 : 1, 11, 47, 517
979 : 1, 11, 89, 979
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 517,979,438, is 1.
Now, the common factors can be found like this.
517:11x 47
979:11x 89
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.
11 = 11
Therefore, the value for common factors is 11.
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 = 221690634/(1x11)
LCM = 221690634/11
LCM = 20153694
Thus, we can understand that the LCM of 517,979,438 is 20153694.
