Given numbers are 326,854,420,260
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 326,854,420,260 is 54288780.
Find LCM of 326,854,420,260 with Prime Factorization
2 | 326, 854, 420, 260 |
2 | 163, 427, 210, 130 |
5 | 163, 427, 105, 65 |
7 | 163, 427, 21, 13 |
163, 61, 3, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 163 x 61 x 3 x 13 = 54288780
Therefore, the lowest common multiple of 326,854,420,260 is 54288780.
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.
326 x 854 x 420 x 260 = 30401716800
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.
326 : 1, 2, 163, 326
854 : 1, 2, 7, 14, 61, 122, 427, 854
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 326,854,420,260, is 2.
Now, the common factors can be found like this.
326:2x 163
854:2x 7x 61
420:2x 2x 3x 5x 7
260:2x 2x 5x 13
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 2x 5x 7 = 280
Therefore, the value for common factors is 280.
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 = 30401716800/(2x280)
LCM = 30401716800/560
LCM = 54288780
Thus, we can understand that the LCM of 326,854,420,260 is 54288780.
