Given numbers are 747,891,430,124,198
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 747,891,430,124,198 is 1971586980.
Find LCM of 747,891,430,124,198 with Prime Factorization
| 2 | 747, 891, 430, 124, 198 |
| 3 | 747, 891, 215, 62, 99 |
| 3 | 249, 297, 215, 62, 33 |
| 11 | 83, 99, 215, 62, 11 |
| 83, 9, 215, 62, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 83 x 9 x 215 x 62 x 1 = 1971586980
Therefore, the lowest common multiple of 747,891,430,124,198 is 1971586980.
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 430 x 124 x 198 = 7026735996720
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
430 : 1, 2, 5, 10, 43, 86, 215, 430
124 : 1, 2, 4, 31, 62, 124
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 747,891,430,124,198, is 1.
Now, the common factors can be found like this.
747:3x 3x 83
891:3x 3x 3x 3x 11
430:2x 5x 43
124:2x 2x 31
198:2x 3x 3x 11
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 3x 3x 3x 11 = 3564
Therefore, the value for common factors is 3564.
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 = 7026735996720/(1x3564)
LCM = 7026735996720/3564
LCM = 1971586980
Thus, we can understand that the LCM of 747,891,430,124,198 is 1971586980.
