Given numbers are 438,949,491
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 438,949,491 is 2795754.
Find LCM of 438,949,491 with Prime Factorization
73 | 438, 949, 491 |
6, 13, 491 |
Multiply the prime numbers at the bottom and the left side.
73 x 6 x 13 x 491 = 2795754
Therefore, the lowest common multiple of 438,949,491 is 2795754.
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.
438 x 949 x 491 = 204090042
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.
438 : 1, 2, 3, 6, 73, 146, 219, 438
949 : 1, 13, 73, 949
491 : 1, 491
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 438,949,491, is 1.
Now, the common factors can be found like this.
438:2x 3x 73
949:13x 73
491:491
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
73 = 73
Therefore, the value for common factors is 73.
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 = 204090042/(1x73)
LCM = 204090042/73
LCM = 2795754
Thus, we can understand that the LCM of 438,949,491 is 2795754.
