Given numbers are 550,623,687,438,154
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 550,623,687,438,154 is 17184240150.
Find LCM of 550,623,687,438,154 with Prime Factorization
| 2 | 550, 623, 687, 438, 154 |
| 3 | 275, 623, 687, 219, 77 |
| 7 | 275, 623, 229, 73, 77 |
| 11 | 275, 89, 229, 73, 11 |
| 25, 89, 229, 73, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 11 x 25 x 89 x 229 x 73 x 1 = 17184240150
Therefore, the lowest common multiple of 550,623,687,438,154 is 17184240150.
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.
550 x 623 x 687 x 438 x 154 = 15878237898600
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.
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
623 : 1, 7, 89, 623
687 : 1, 3, 229, 687
438 : 1, 2, 3, 6, 73, 146, 219, 438
154 : 1, 2, 7, 11, 14, 22, 77, 154
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 550,623,687,438,154, is 1.
Now, the common factors can be found like this.
550:2x 5x 5x 11
623:7x 89
687:3x 229
438:2x 3x 73
154:2x 7x 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 7x 11 = 924
Therefore, the value for common factors is 924.
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 = 15878237898600/(1x924)
LCM = 15878237898600/924
LCM = 17184240150
Thus, we can understand that the LCM of 550,623,687,438,154 is 17184240150.
