Given numbers are 665,651,988,921,273
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 665,651,988,921,273 is 987293580.
Find LCM of 665,651,988,921,273 with Prime Factorization
| 3 | 665, 651, 988, 921, 273 |
| 7 | 665, 217, 988, 307, 91 |
| 13 | 95, 31, 988, 307, 13 |
| 19 | 95, 31, 76, 307, 1 |
| 5, 31, 4, 307, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 13 x 19 x 5 x 31 x 4 x 307 x 1 = 987293580
Therefore, the lowest common multiple of 665,651,988,921,273 is 987293580.
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.
665 x 651 x 988 x 921 x 273 = 107542927788660
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.
665 : 1, 5, 7, 19, 35, 95, 133, 665
651 : 1, 3, 7, 21, 31, 93, 217, 651
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
921 : 1, 3, 307, 921
273 : 1, 3, 7, 13, 21, 39, 91, 273
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,651,988,921,273, is 1.
Now, the common factors can be found like this.
665:5x 7x 19
651:3x 7x 31
988:2x 2x 13x 19
921:3x 307
273:3x 7x 13
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 7x 7x 13x 19 = 108927
Therefore, the value for common factors is 108927.
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 = 107542927788660/(1x108927)
LCM = 107542927788660/108927
LCM = 987293580
Thus, we can understand that the LCM of 665,651,988,921,273 is 987293580.
