Given numbers are 691,933,442,144,100
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 691,933,442,144,100 is 170975235600.
Find LCM of 691,933,442,144,100 with Prime Factorization
| 2 | 691, 933, 442, 144, 100 |
| 2 | 691, 933, 221, 72, 50 |
| 3 | 691, 933, 221, 36, 25 |
| 691, 311, 221, 12, 25 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 691 x 311 x 221 x 12 x 25 = 170975235600
Therefore, the lowest common multiple of 691,933,442,144,100 is 170975235600.
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.
691 x 933 x 442 x 144 x 100 = 4103405654400
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.
691 : 1, 691
933 : 1, 3, 311, 933
442 : 1, 2, 13, 17, 26, 34, 221, 442
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 691,933,442,144,100, is 1.
Now, the common factors can be found like this.
691:691
933:3x 311
442:2x 13x 17
144:2x 2x 2x 2x 3x 3
100:2x 2x 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.
2x 2x 2x 3 = 24
Therefore, the value for common factors is 24.
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 = 4103405654400/(1x24)
LCM = 4103405654400/24
LCM = 170975235600
Thus, we can understand that the LCM of 691,933,442,144,100 is 170975235600.
