Given numbers are 644,981,545,743,809
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 644,981,545,743,809 is 1898725637340.
Find LCM of 644,981,545,743,809 with Prime Factorization
109 | 644, 981, 545, 743, 809 |
644, 9, 5, 743, 809 |
Multiply the prime numbers at the bottom and the left side.
109 x 644 x 9 x 5 x 743 x 809 = 1898725637340
Therefore, the lowest common multiple of 644,981,545,743,809 is 1898725637340.
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 981 x 545 x 743 x 809 = 206961094470060
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
981 : 1, 3, 9, 109, 327, 981
545 : 1, 5, 109, 545
743 : 1, 743
809 : 1, 809
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,981,545,743,809, is 1.
Now, the common factors can be found like this.
644:2x 2x 7x 23
981:3x 3x 109
545:5x 109
743:743
809:809
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
109 = 109
Therefore, the value for common factors is 109.
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 = 206961094470060/(1x109)
LCM = 206961094470060/109
LCM = 1898725637340
Thus, we can understand that the LCM of 644,981,545,743,809 is 1898725637340.
