Given numbers are 289,742,901,949
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 289,742,901,949 is 203501662.
Find LCM of 289,742,901,949 with Prime Factorization
17 | 289, 742, 901, 949 |
53 | 17, 742, 53, 949 |
17, 14, 1, 949 |
Multiply the prime numbers at the bottom and the left side.
17 x 53 x 17 x 14 x 1 x 949 = 203501662
Therefore, the lowest common multiple of 289,742,901,949 is 203501662.
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.
289 x 742 x 901 x 949 = 183354997462
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.
289 : 1, 17, 289
742 : 1, 2, 7, 14, 53, 106, 371, 742
901 : 1, 17, 53, 901
949 : 1, 13, 73, 949
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 289,742,901,949, is 1.
Now, the common factors can be found like this.
289:17x 17
742:2x 7x 53
901:17x 53
949:13x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17x 53 = 901
Therefore, the value for common factors is 901.
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 = 183354997462/(1x901)
LCM = 183354997462/901
LCM = 203501662
Thus, we can understand that the LCM of 289,742,901,949 is 203501662.
