Given numbers are 855,252,769,437
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 855,252,769,437 is 423426780.
Find LCM of 855,252,769,437 with Prime Factorization
| 3 | 855, 252, 769, 437 |
| 3 | 285, 84, 769, 437 |
| 19 | 95, 28, 769, 437 |
| 5, 28, 769, 23 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 19 x 5 x 28 x 769 x 23 = 423426780
Therefore, the lowest common multiple of 855,252,769,437 is 423426780.
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.
855 x 252 x 769 x 437 = 72405979380
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.
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
769 : 1, 769
437 : 1, 19, 23, 437
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,252,769,437, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
252:2x 2x 3x 3x 7
769:769
437:19x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 19 = 171
Therefore, the value for common factors is 171.
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 = 72405979380/(1x171)
LCM = 72405979380/171
LCM = 423426780
Thus, we can understand that the LCM of 855,252,769,437 is 423426780.
