Given numbers are 218,817,545,685
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 218,817,545,685 is 122002610.
Find LCM of 218,817,545,685 with Prime Factorization
5 | 218, 817, 545, 685 |
109 | 218, 817, 109, 137 |
2, 817, 1, 137 |
Multiply the prime numbers at the bottom and the left side.
5 x 109 x 2 x 817 x 1 x 137 = 122002610
Therefore, the lowest common multiple of 218,817,545,685 is 122002610.
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.
218 x 817 x 545 x 685 = 66491422450
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.
218 : 1, 2, 109, 218
817 : 1, 19, 43, 817
545 : 1, 5, 109, 545
685 : 1, 5, 137, 685
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 218,817,545,685, is 1.
Now, the common factors can be found like this.
218:2x 109
817:19x 43
545:5x 109
685:5x 137
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 109 = 545
Therefore, the value for common factors is 545.
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 = 66491422450/(1x545)
LCM = 66491422450/545
LCM = 122002610
Thus, we can understand that the LCM of 218,817,545,685 is 122002610.
