The LCM of 220,385,723,868 is 34516020.
Find LCM of 220,385,723,868 with Prime Factorization
2 | 220, 385, 723, 868 |
2 | 110, 385, 723, 434 |
5 | 55, 385, 723, 217 |
7 | 11, 77, 723, 217 |
11 | 11, 11, 723, 31 |
1, 1, 723, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 11 x 1 x 1 x 723 x 31 = 34516020
Therefore, the lowest common multiple of 220,385,723,868 is 34516020.
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.
220 x 385 x 723 x 868 = 53154670800
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.
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
385 : 1, 5, 7, 11, 35, 55, 77, 385
723 : 1, 3, 241, 723
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 220,385,723,868, is 1.
Now, the common factors can be found like this.
220:2x 2x 5x 11
385:5x 7x 11
723:3x 241
868:2x 2x 7x 31
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 5x 7x 11 = 1540
Therefore, the value for common factors is 1540.
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 = 53154670800/(1x1540)
LCM = 53154670800/1540
LCM = 34516020
Thus, we can understand that the LCM of 220,385,723,868 is 34516020.
