Given numbers are 665,245,165,746
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 665,245,165,746 is 114596790.
Find LCM of 665,245,165,746 with Prime Factorization
| 5 | 665, 245, 165, 746 |
| 7 | 133, 49, 33, 746 |
| 19, 7, 33, 746 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 19 x 7 x 33 x 746 = 114596790
Therefore, the lowest common multiple of 665,245,165,746 is 114596790.
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 245 x 165 x 746 = 20054438250
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
245 : 1, 5, 7, 35, 49, 245
165 : 1, 3, 5, 11, 15, 33, 55, 165
746 : 1, 2, 373, 746
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,245,165,746, is 1.
Now, the common factors can be found like this.
665:5x 7x 19
245:5x 7x 7
165:3x 5x 11
746:2x 373
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 7 = 175
Therefore, the value for common factors is 175.
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 = 20054438250/(1x175)
LCM = 20054438250/175
LCM = 114596790
Thus, we can understand that the LCM of 665,245,165,746 is 114596790.
