Given numbers are 479,772,218,921
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 479,772,218,921 is 37122647532.
Find LCM of 479,772,218,921 with Prime Factorization
| 2 | 479, 772, 218, 921 |
| 479, 386, 109, 921 |
Multiply the prime numbers at the bottom and the left side.
2 x 479 x 386 x 109 x 921 = 37122647532
Therefore, the lowest common multiple of 479,772,218,921 is 37122647532.
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.
479 x 772 x 218 x 921 = 74245295064
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.
479 : 1, 479
772 : 1, 2, 4, 193, 386, 772
218 : 1, 2, 109, 218
921 : 1, 3, 307, 921
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 479,772,218,921, is 1.
Now, the common factors can be found like this.
479:479
772:2x 2x 193
218:2x 109
921:3x 307
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 74245295064/(1x2)
LCM = 74245295064/2
LCM = 37122647532
Thus, we can understand that the LCM of 479,772,218,921 is 37122647532.
