Given numbers are 770,902,682,158
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 770,902,682,158 is 77314930.
Find LCM of 770,902,682,158 with Prime Factorization
| 2 | 770, 902, 682, 158 |
| 11 | 385, 451, 341, 79 |
| 35, 41, 31, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 35 x 41 x 31 x 79 = 77314930
Therefore, the lowest common multiple of 770,902,682,158 is 77314930.
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 902 x 682 x 158 = 74840852240
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
902 : 1, 2, 11, 22, 41, 82, 451, 902
682 : 1, 2, 11, 22, 31, 62, 341, 682
158 : 1, 2, 79, 158
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,902,682,158, is 2.
Now, the common factors can be found like this.
770:2x 5x 7x 11
902:2x 11x 41
682:2x 11x 31
158:2x 79
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 11x 11 = 484
Therefore, the value for common factors is 484.
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 = 74840852240/(2x484)
LCM = 74840852240/968
LCM = 77314930
Thus, we can understand that the LCM of 770,902,682,158 is 77314930.
