Given numbers are 326,221,918,772
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 326,221,918,772 is 750863412.
Find LCM of 326,221,918,772 with Prime Factorization
| 2 | 326, 221, 918, 772 |
| 17 | 163, 221, 459, 386 |
| 163, 13, 27, 386 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 163 x 13 x 27 x 386 = 750863412
Therefore, the lowest common multiple of 326,221,918,772 is 750863412.
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 221 x 918 x 772 = 51058712016
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
221 : 1, 13, 17, 221
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
772 : 1, 2, 4, 193, 386, 772
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 326,221,918,772, is 1.
Now, the common factors can be found like this.
326:2x 163
221:13x 17
918:2x 3x 3x 3x 17
772:2x 2x 193
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 17 = 68
Therefore, the value for common factors is 68.
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 = 51058712016/(1x68)
LCM = 51058712016/68
LCM = 750863412
Thus, we can understand that the LCM of 326,221,918,772 is 750863412.
