Given numbers are 770,629,979,534,661
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 770,629,979,534,661 is 85477948710.
Find LCM of 770,629,979,534,661 with Prime Factorization
| 2 | 770, 629, 979, 534, 661 |
| 11 | 385, 629, 979, 267, 661 |
| 89 | 35, 629, 89, 267, 661 |
| 35, 629, 1, 3, 661 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 89 x 35 x 629 x 1 x 3 x 661 = 85477948710
Therefore, the lowest common multiple of 770,629,979,534,661 is 85477948710.
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 629 x 979 x 534 x 661 = 167365823574180
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
629 : 1, 17, 37, 629
979 : 1, 11, 89, 979
534 : 1, 2, 3, 6, 89, 178, 267, 534
661 : 1, 661
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,629,979,534,661, is 1.
Now, the common factors can be found like this.
770:2x 5x 7x 11
629:17x 37
979:11x 89
534:2x 3x 89
661:661
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 89 = 1958
Therefore, the value for common factors is 1958.
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 = 167365823574180/(1x1958)
LCM = 167365823574180/1958
LCM = 85477948710
Thus, we can understand that the LCM of 770,629,979,534,661 is 85477948710.
