Given numbers are 935,207,221,690
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 935,207,221,690 is 5032170.
Find LCM of 935,207,221,690 with Prime Factorization
3 | 935, 207, 221, 690 |
5 | 935, 69, 221, 230 |
17 | 187, 69, 221, 46 |
23 | 11, 69, 13, 46 |
11, 3, 13, 2 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 17 x 23 x 11 x 3 x 13 x 2 = 5032170
Therefore, the lowest common multiple of 935,207,221,690 is 5032170.
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.
935 x 207 x 221 x 690 = 29513677050
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.
935 : 1, 5, 11, 17, 55, 85, 187, 935
207 : 1, 3, 9, 23, 69, 207
221 : 1, 13, 17, 221
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 935,207,221,690, is 1.
Now, the common factors can be found like this.
935:5x 11x 17
207:3x 3x 23
221:13x 17
690:2x 3x 5x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 17x 23 = 5865
Therefore, the value for common factors is 5865.
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 = 29513677050/(1x5865)
LCM = 29513677050/5865
LCM = 5032170
Thus, we can understand that the LCM of 935,207,221,690 is 5032170.
