The LCM of 748,648,451,856 is 531599112.
Find LCM of 748,648,451,856 with Prime Factorization
| 2 | 748, 648, 451, 856 |
| 2 | 374, 324, 451, 428 |
| 2 | 187, 162, 451, 214 |
| 11 | 187, 81, 451, 107 |
| 17, 81, 41, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 11 x 17 x 81 x 41 x 107 = 531599112
Therefore, the lowest common multiple of 748,648,451,856 is 531599112.
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 648 x 451 x 856 = 187122887424
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
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
451 : 1, 11, 41, 451
856 : 1, 2, 4, 8, 107, 214, 428, 856
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 748,648,451,856, is 1.
Now, the common factors can be found like this.
748:2x 2x 11x 17
648:2x 2x 2x 3x 3x 3x 3
451:11x 41
856:2x 2x 2x 107
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 11 = 352
Therefore, the value for common factors is 352.
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 = 187122887424/(1x352)
LCM = 187122887424/352
LCM = 531599112
Thus, we can understand that the LCM of 748,648,451,856 is 531599112.
