Find LCM of 770,858,255,763 with Prime Factorization
| 2 | 770, 858, 255, 763 |
| 3 | 385, 429, 255, 763 |
| 5 | 385, 143, 85, 763 |
| 7 | 77, 143, 17, 763 |
| 11 | 11, 143, 17, 109 |
| 1, 13, 17, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 11 x 1 x 13 x 17 x 109 = 55645590
Therefore, the lowest common multiple of 770,858,255,763 is 55645590.
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 858 x 255 x 763 = 128541312900
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
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
255 : 1, 3, 5, 15, 17, 51, 85, 255
763 : 1, 7, 109, 763
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,858,255,763, is 1.
Now, the common factors can be found like this.
770:2x 5x 7x 11
858:2x 3x 11x 13
255:3x 5x 17
763:7x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 7x 11 = 2310
Therefore, the value for common factors is 2310.
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 = 128541312900/(1x2310)
LCM = 128541312900/2310
LCM = 55645590
Thus, we can understand that the LCM of 770,858,255,763 is 55645590.
