Given numbers are 782,981,706,576
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 782,981,706,576 is 8665636032.
Find LCM of 782,981,706,576 with Prime Factorization
| 2 | 782, 981, 706, 576 |
| 3 | 391, 981, 353, 288 |
| 3 | 391, 327, 353, 96 |
| 391, 109, 353, 32 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 391 x 109 x 353 x 32 = 8665636032
Therefore, the lowest common multiple of 782,981,706,576 is 8665636032.
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.
782 x 981 x 706 x 576 = 311962897152
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.
782 : 1, 2, 17, 23, 34, 46, 391, 782
981 : 1, 3, 9, 109, 327, 981
706 : 1, 2, 353, 706
576 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 64, 72, 96, 144, 192, 288, 576
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,981,706,576, is 1.
Now, the common factors can be found like this.
782:2x 17x 23
981:3x 3x 109
706:2x 353
576:2x 2x 2x 2x 2x 2x 3x 3
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 3x 3 = 36
Therefore, the value for common factors is 36.
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 = 311962897152/(1x36)
LCM = 311962897152/36
LCM = 8665636032
Thus, we can understand that the LCM of 782,981,706,576 is 8665636032.
