Given numbers are 403,552,713,979
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 403,552,713,979 is 217784424.
Find LCM of 403,552,713,979 with Prime Factorization
| 23 | 403, 552, 713, 979 |
| 31 | 403, 24, 31, 979 |
| 13, 24, 1, 979 |
Multiply the prime numbers at the bottom and the left side.
23 x 31 x 13 x 24 x 1 x 979 = 217784424
Therefore, the lowest common multiple of 403,552,713,979 is 217784424.
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.
403 x 552 x 713 x 979 = 155280294312
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.
403 : 1, 13, 31, 403
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
713 : 1, 23, 31, 713
979 : 1, 11, 89, 979
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,552,713,979, is 1.
Now, the common factors can be found like this.
403:13x 31
552:2x 2x 2x 3x 23
713:23x 31
979:11x 89
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23x 31 = 713
Therefore, the value for common factors is 713.
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 = 155280294312/(1x713)
LCM = 155280294312/713
LCM = 217784424
Thus, we can understand that the LCM of 403,552,713,979 is 217784424.
