Given numbers are 865,778,228,399
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 865,778,228,399 is 537030060.
Find LCM of 865,778,228,399 with Prime Factorization
| 2 | 865, 778, 228, 399 |
| 3 | 865, 389, 114, 399 |
| 19 | 865, 389, 38, 133 |
| 865, 389, 2, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 865 x 389 x 2 x 7 = 537030060
Therefore, the lowest common multiple of 865,778,228,399 is 537030060.
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.
865 x 778 x 228 x 399 = 61221426840
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.
865 : 1, 5, 173, 865
778 : 1, 2, 389, 778
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
399 : 1, 3, 7, 19, 21, 57, 133, 399
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 865,778,228,399, is 1.
Now, the common factors can be found like this.
865:5x 173
778:2x 389
228:2x 2x 3x 19
399:3x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 19 = 114
Therefore, the value for common factors is 114.
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 = 61221426840/(1x114)
LCM = 61221426840/114
LCM = 537030060
Thus, we can understand that the LCM of 865,778,228,399 is 537030060.
