Given numbers are 452,386,949,772,920
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 452,386,949,772,920 is 19041001720.
Find LCM of 452,386,949,772,920 with Prime Factorization
| 2 | 452, 386, 949, 772, 920 |
| 2 | 226, 193, 949, 386, 460 |
| 193 | 113, 193, 949, 193, 230 |
| 113, 1, 949, 1, 230 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 193 x 113 x 1 x 949 x 1 x 230 = 19041001720
Therefore, the lowest common multiple of 452,386,949,772,920 is 19041001720.
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.
452 x 386 x 949 x 772 x 920 = 117597226622720
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.
452 : 1, 2, 4, 113, 226, 452
386 : 1, 2, 193, 386
949 : 1, 13, 73, 949
772 : 1, 2, 4, 193, 386, 772
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 452,386,949,772,920, is 1.
Now, the common factors can be found like this.
452:2x 2x 113
386:2x 193
949:13x 73
772:2x 2x 193
920:2x 2x 2x 5x 23
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 2x 2x 2x 193 = 6176
Therefore, the value for common factors is 6176.
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 = 117597226622720/(1x6176)
LCM = 117597226622720/6176
LCM = 19041001720
Thus, we can understand that the LCM of 452,386,949,772,920 is 19041001720.
