Find LCM of 770,505,638,286,595 with Prime Factorization
| 2 | 770, 505, 638, 286, 595 |
| 5 | 385, 505, 319, 143, 595 |
| 7 | 77, 101, 319, 143, 119 |
| 11 | 11, 101, 319, 143, 17 |
| 1, 101, 29, 13, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 11 x 1 x 101 x 29 x 13 x 17 = 498427930
Therefore, the lowest common multiple of 770,505,638,286,595 is 498427930.
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.
770 x 505 x 638 x 286 x 595 = 42216845671000
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.
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
505 : 1, 5, 101, 505
638 : 1, 2, 11, 22, 29, 58, 319, 638
286 : 1, 2, 11, 13, 22, 26, 143, 286
595 : 1, 5, 7, 17, 35, 85, 119, 595
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,505,638,286,595, is 1.
Now, the common factors can be found like this.
770:2x 5x 7x 11
505:5x 101
638:2x 11x 29
286:2x 11x 13
595:5x 7x 17
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 5x 5x 7x 11x 11 = 84700
Therefore, the value for common factors is 84700.
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 = 42216845671000/(1x84700)
LCM = 42216845671000/84700
LCM = 498427930
Thus, we can understand that the LCM of 770,505,638,286,595 is 498427930.
