Given numbers are 458,145,781,964,920
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 458,145,781,964,920 is 1149977608120.
Find LCM of 458,145,781,964,920 with Prime Factorization
| 2 | 458, 145, 781, 964, 920 |
| 2 | 229, 145, 781, 482, 460 |
| 5 | 229, 145, 781, 241, 230 |
| 229, 29, 781, 241, 46 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 229 x 29 x 781 x 241 x 46 = 1149977608120
Therefore, the lowest common multiple of 458,145,781,964,920 is 1149977608120.
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.
458 x 145 x 781 x 964 x 920 = 45999104324800
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.
458 : 1, 2, 229, 458
145 : 1, 5, 29, 145
781 : 1, 11, 71, 781
964 : 1, 2, 4, 241, 482, 964
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 458,145,781,964,920, is 1.
Now, the common factors can be found like this.
458:2x 229
145:5x 29
781:11x 71
964:2x 2x 241
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 5 = 40
Therefore, the value for common factors is 40.
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 = 45999104324800/(1x40)
LCM = 45999104324800/40
LCM = 1149977608120
Thus, we can understand that the LCM of 458,145,781,964,920 is 1149977608120.
