Given numbers are 573,978,221,326
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 573,978,221,326 is 41282358.
Find LCM of 573,978,221,326 with Prime Factorization
| 2 | 573, 978, 221, 326 |
| 3 | 573, 489, 221, 163 |
| 163 | 191, 163, 221, 163 |
| 191, 1, 221, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 163 x 191 x 1 x 221 x 1 = 41282358
Therefore, the lowest common multiple of 573,978,221,326 is 41282358.
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.
573 x 978 x 221 x 326 = 40374146124
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.
573 : 1, 3, 191, 573
978 : 1, 2, 3, 6, 163, 326, 489, 978
221 : 1, 13, 17, 221
326 : 1, 2, 163, 326
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 573,978,221,326, is 1.
Now, the common factors can be found like this.
573:3x 191
978:2x 3x 163
221:13x 17
326:2x 163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 163 = 978
Therefore, the value for common factors is 978.
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 = 40374146124/(1x978)
LCM = 40374146124/978
LCM = 41282358
Thus, we can understand that the LCM of 573,978,221,326 is 41282358.
