Given numbers are 207,721,824,874
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 207,721,824,874 is 22685544.
Find LCM of 207,721,824,874 with Prime Factorization
| 2 | 207, 721, 824, 874 |
| 23 | 207, 721, 412, 437 |
| 103 | 9, 721, 412, 19 |
| 9, 7, 4, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 23 x 103 x 9 x 7 x 4 x 19 = 22685544
Therefore, the lowest common multiple of 207,721,824,874 is 22685544.
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.
207 x 721 x 824 x 874 = 107484107472
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.
207 : 1, 3, 9, 23, 69, 207
721 : 1, 7, 103, 721
824 : 1, 2, 4, 8, 103, 206, 412, 824
874 : 1, 2, 19, 23, 38, 46, 437, 874
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 207,721,824,874, is 1.
Now, the common factors can be found like this.
207:3x 3x 23
721:7x 103
824:2x 2x 2x 103
874:2x 19x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 23x 103 = 4738
Therefore, the value for common factors is 4738.
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 = 107484107472/(1x4738)
LCM = 107484107472/4738
LCM = 22685544
Thus, we can understand that the LCM of 207,721,824,874 is 22685544.
