Given numbers are 747,856,249,891,375
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 747,856,249,891,375 is 7912971000.
Find LCM of 747,856,249,891,375 with Prime Factorization
| 3 | 747, 856, 249, 891, 375 |
| 3 | 249, 856, 83, 297, 125 |
| 83 | 83, 856, 83, 99, 125 |
| 1, 856, 1, 99, 125 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 83 x 1 x 856 x 1 x 99 x 125 = 7912971000
Therefore, the lowest common multiple of 747,856,249,891,375 is 7912971000.
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.
747 x 856 x 249 x 891 x 375 = 53198904033000
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.
747 : 1, 3, 9, 83, 249, 747
856 : 1, 2, 4, 8, 107, 214, 428, 856
249 : 1, 3, 83, 249
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
375 : 1, 3, 5, 15, 25, 75, 125, 375
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 747,856,249,891,375, is 1.
Now, the common factors can be found like this.
747:3x 3x 83
856:2x 2x 2x 107
249:3x 83
891:3x 3x 3x 3x 11
375:3x 5x 5x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 83 = 6723
Therefore, the value for common factors is 6723.
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 = 53198904033000/(1x6723)
LCM = 53198904033000/6723
LCM = 7912971000
Thus, we can understand that the LCM of 747,856,249,891,375 is 7912971000.
