Given numbers are 748,680,433,864
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 748,680,433,864 is 349794720.
Find LCM of 748,680,433,864 with Prime Factorization
| 2 | 748, 680, 433, 864 |
| 2 | 374, 340, 433, 432 |
| 2 | 187, 170, 433, 216 |
| 17 | 187, 85, 433, 108 |
| 11, 5, 433, 108 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 17 x 11 x 5 x 433 x 108 = 349794720
Therefore, the lowest common multiple of 748,680,433,864 is 349794720.
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.
748 x 680 x 433 x 864 = 190288327680
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.
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
433 : 1, 433
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 748,680,433,864, is 1.
Now, the common factors can be found like this.
748:2x 2x 11x 17
680:2x 2x 2x 5x 17
433:433
864:2x 2x 2x 2x 2x 3x 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 2x 2x 2x 17 = 544
Therefore, the value for common factors is 544.
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 = 190288327680/(1x544)
LCM = 190288327680/544
LCM = 349794720
Thus, we can understand that the LCM of 748,680,433,864 is 349794720.
