Find LCM of 665,445,561,404,528 with Prime Factorization
| 2 | 665, 445, 561, 404, 528 |
| 2 | 665, 445, 561, 202, 264 |
| 3 | 665, 445, 561, 101, 132 |
| 5 | 665, 445, 187, 101, 44 |
| 11 | 133, 89, 187, 101, 44 |
| 133, 89, 17, 101, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 11 x 133 x 89 x 17 x 101 x 4 = 53655700560
Therefore, the lowest common multiple of 665,445,561,404,528 is 53655700560.
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 445 x 561 x 404 x 528 = 35412762369600
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
445 : 1, 5, 89, 445
561 : 1, 3, 11, 17, 33, 51, 187, 561
404 : 1, 2, 4, 101, 202, 404
528 : 1, 2, 3, 4, 6, 8, 11, 12, 16, 22, 24, 33, 44, 48, 66, 88, 132, 176, 264, 528
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,445,561,404,528, is 1.
Now, the common factors can be found like this.
665:5x 7x 19
445:5x 89
561:3x 11x 17
404:2x 2x 101
528:2x 2x 2x 2x 3x 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 5x 11 = 660
Therefore, the value for common factors is 660.
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 = 35412762369600/(1x660)
LCM = 35412762369600/660
LCM = 53655700560
Thus, we can understand that the LCM of 665,445,561,404,528 is 53655700560.
