Given numbers are 392,936,386,957
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 392,936,386,957 is 2823708888.
Find LCM of 392,936,386,957 with Prime Factorization
| 2 | 392, 936, 386, 957 |
| 2 | 196, 468, 193, 957 |
| 2 | 98, 234, 193, 957 |
| 3 | 49, 117, 193, 957 |
| 49, 39, 193, 319 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 49 x 39 x 193 x 319 = 2823708888
Therefore, the lowest common multiple of 392,936,386,957 is 2823708888.
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.
392 x 936 x 386 x 957 = 135538026624
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.
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936
386 : 1, 2, 193, 386
957 : 1, 3, 11, 29, 33, 87, 319, 957
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 392,936,386,957, is 1.
Now, the common factors can be found like this.
392:2x 2x 2x 7x 7
936:2x 2x 2x 3x 3x 13
386:2x 193
957:3x 11x 29
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 3 = 48
Therefore, the value for common factors is 48.
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 = 135538026624/(1x48)
LCM = 135538026624/48
LCM = 2823708888
Thus, we can understand that the LCM of 392,936,386,957 is 2823708888.
