Given numbers are 395,252,752,654,138
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 395,252,752,654,138 is 46914794640.
Find LCM of 395,252,752,654,138 with Prime Factorization
| 2 | 395, 252, 752, 654, 138 |
| 2 | 395, 126, 376, 327, 69 |
| 3 | 395, 63, 188, 327, 69 |
| 395, 21, 188, 109, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 395 x 21 x 188 x 109 x 23 = 46914794640
Therefore, the lowest common multiple of 395,252,752,654,138 is 46914794640.
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.
395 x 252 x 752 x 654 x 138 = 6755730428160
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.
395 : 1, 5, 79, 395
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
752 : 1, 2, 4, 8, 16, 47, 94, 188, 376, 752
654 : 1, 2, 3, 6, 109, 218, 327, 654
138 : 1, 2, 3, 6, 23, 46, 69, 138
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 395,252,752,654,138, is 1.
Now, the common factors can be found like this.
395:5x 79
252:2x 2x 3x 3x 7
752:2x 2x 2x 2x 47
654:2x 3x 109
138:2x 3x 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 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 6755730428160/(1x144)
LCM = 6755730428160/144
LCM = 46914794640
Thus, we can understand that the LCM of 395,252,752,654,138 is 46914794640.
