Given numbers are 579,236,386,644
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 579,236,386,644 is 21999684.
Find LCM of 579,236,386,644 with Prime Factorization
| 2 | 579, 236, 386, 644 |
| 2 | 579, 118, 193, 322 |
| 193 | 579, 59, 193, 161 |
| 3, 59, 1, 161 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 193 x 3 x 59 x 1 x 161 = 21999684
Therefore, the lowest common multiple of 579,236,386,644 is 21999684.
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.
579 x 236 x 386 x 644 = 33967512096
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.
579 : 1, 3, 193, 579
236 : 1, 2, 4, 59, 118, 236
386 : 1, 2, 193, 386
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 579,236,386,644, is 1.
Now, the common factors can be found like this.
579:3x 193
236:2x 2x 59
386:2x 193
644:2x 2x 7x 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 193 = 1544
Therefore, the value for common factors is 1544.
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 = 33967512096/(1x1544)
LCM = 33967512096/1544
LCM = 21999684
Thus, we can understand that the LCM of 579,236,386,644 is 21999684.
