Given numbers are 649,644,828,807,288
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 649,644,828,807,288 is 8094971808.
Find LCM of 649,644,828,807,288 with Prime Factorization
| 2 | 649, 644, 828, 807, 288 |
| 2 | 649, 322, 414, 807, 144 |
| 3 | 649, 161, 207, 807, 72 |
| 3 | 649, 161, 69, 269, 24 |
| 23 | 649, 161, 23, 269, 8 |
| 649, 7, 1, 269, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 23 x 649 x 7 x 1 x 269 x 8 = 8094971808
Therefore, the lowest common multiple of 649,644,828,807,288 is 8094971808.
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.
649 x 644 x 828 x 807 x 288 = 80431639884288
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.
649 : 1, 11, 59, 649
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
807 : 1, 3, 269, 807
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,644,828,807,288, is 1.
Now, the common factors can be found like this.
649:11x 59
644:2x 2x 7x 23
828:2x 2x 3x 3x 23
807:3x 269
288:2x 2x 2x 2x 2x 3x 3
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 3x 3x 23 = 9936
Therefore, the value for common factors is 9936.
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 = 80431639884288/(1x9936)
LCM = 80431639884288/9936
LCM = 8094971808
Thus, we can understand that the LCM of 649,644,828,807,288 is 8094971808.
