Given numbers are 747,891,782,996,387
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 747,891,782,996,387 is 4973487156.
Find LCM of 747,891,782,996,387 with Prime Factorization
| 2 | 747, 891, 782, 996, 387 |
| 3 | 747, 891, 391, 498, 387 |
| 3 | 249, 297, 391, 166, 129 |
| 83 | 83, 99, 391, 166, 43 |
| 1, 99, 391, 2, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 83 x 1 x 99 x 391 x 2 x 43 = 4973487156
Therefore, the lowest common multiple of 747,891,782,996,387 is 4973487156.
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 891 x 782 x 996 x 387 = 200620524898728
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
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
782 : 1, 2, 17, 23, 34, 46, 391, 782
996 : 1, 2, 3, 4, 6, 12, 83, 166, 249, 332, 498, 996
387 : 1, 3, 9, 43, 129, 387
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 747,891,782,996,387, is 1.
Now, the common factors can be found like this.
747:3x 3x 83
891:3x 3x 3x 3x 11
782:2x 17x 23
996:2x 2x 3x 83
387:3x 3x 43
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 3x 3x 3x 3x 83 = 40338
Therefore, the value for common factors is 40338.
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 = 200620524898728/(1x40338)
LCM = 200620524898728/40338
LCM = 4973487156
Thus, we can understand that the LCM of 747,891,782,996,387 is 4973487156.
