Given numbers are 279,504,858,644
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 279,504,858,644 is 51387336.
Find LCM of 279,504,858,644 with Prime Factorization
| 2 | 279, 504, 858, 644 |
| 2 | 279, 252, 429, 322 |
| 3 | 279, 126, 429, 161 |
| 3 | 93, 42, 143, 161 |
| 7 | 31, 14, 143, 161 |
| 31, 2, 143, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 7 x 31 x 2 x 143 x 23 = 51387336
Therefore, the lowest common multiple of 279,504,858,644 is 51387336.
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.
279 x 504 x 858 x 644 = 77697652032
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.
279 : 1, 3, 9, 31, 93, 279
504 : 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
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 279,504,858,644, is 1.
Now, the common factors can be found like this.
279:3x 3x 31
504:2x 2x 2x 3x 3x 7
858:2x 3x 11x 13
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 3x 3x 3x 7 = 1512
Therefore, the value for common factors is 1512.
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 = 77697652032/(1x1512)
LCM = 77697652032/1512
LCM = 51387336
Thus, we can understand that the LCM of 279,504,858,644 is 51387336.
