The LCM of 445,424,691,770,315 is 90351870840.
Find LCM of 445,424,691,770,315 with Prime Factorization
| 2 | 445, 424, 691, 770, 315 |
| 5 | 445, 212, 691, 385, 315 |
| 7 | 89, 212, 691, 77, 63 |
| 89, 212, 691, 11, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 89 x 212 x 691 x 11 x 9 = 90351870840
Therefore, the lowest common multiple of 445,424,691,770,315 is 90351870840.
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 424 x 691 x 770 x 315 = 31623154794000
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
424 : 1, 2, 4, 8, 53, 106, 212, 424
691 : 1, 691
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 445,424,691,770,315, is 1.
Now, the common factors can be found like this.
445:5x 89
424:2x 2x 2x 53
691:691
770:2x 5x 7x 11
315:3x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 7 = 350
Therefore, the value for common factors is 350.
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 = 31623154794000/(1x350)
LCM = 31623154794000/350
LCM = 90351870840
Thus, we can understand that the LCM of 445,424,691,770,315 is 90351870840.
