Given numbers are 644,900,802,911,654
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 644,900,802,911,654 is 5769758465100.
Find LCM of 644,900,802,911,654 with Prime Factorization
| 2 | 644, 900, 802, 911, 654 |
| 2 | 322, 450, 401, 911, 327 |
| 3 | 161, 225, 401, 911, 327 |
| 161, 75, 401, 911, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 161 x 75 x 401 x 911 x 109 = 5769758465100
Therefore, the lowest common multiple of 644,900,802,911,654 is 5769758465100.
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.
644 x 900 x 802 x 911 x 654 = 276948406324800
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.
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
802 : 1, 2, 401, 802
911 : 1, 911
654 : 1, 2, 3, 6, 109, 218, 327, 654
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,900,802,911,654, is 1.
Now, the common factors can be found like this.
644:2x 2x 7x 23
900:2x 2x 3x 3x 5x 5
802:2x 401
911:911
654:2x 3x 109
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 3 = 48
Therefore, the value for common factors is 48.
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 = 276948406324800/(1x48)
LCM = 276948406324800/48
LCM = 5769758465100
Thus, we can understand that the LCM of 644,900,802,911,654 is 5769758465100.
