Find LCM of 445,540,718,774 with Prime Factorization
2 | 445, 540, 718, 774 |
3 | 445, 270, 359, 387 |
3 | 445, 90, 359, 129 |
5 | 445, 30, 359, 43 |
89, 6, 359, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 89 x 6 x 359 x 43 = 741902220
Therefore, the lowest common multiple of 445,540,718,774 is 741902220.
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.
445 x 540 x 718 x 774 = 133542399600
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.
445 : 1, 5, 89, 445
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
718 : 1, 2, 359, 718
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 445,540,718,774, is 1.
Now, the common factors can be found like this.
445:5x 89
540:2x 2x 3x 3x 3x 5
718:2x 359
774:2x 3x 3x 43
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 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 133542399600/(1x180)
LCM = 133542399600/180
LCM = 741902220
Thus, we can understand that the LCM of 445,540,718,774 is 741902220.
