Given numbers are 770,922,121,443
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 770,922,121,443 is 1729768810.
Find LCM of 770,922,121,443 with Prime Factorization
| 2 | 770, 922, 121, 443 |
| 11 | 385, 461, 121, 443 |
| 35, 461, 11, 443 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 35 x 461 x 11 x 443 = 1729768810
Therefore, the lowest common multiple of 770,922,121,443 is 1729768810.
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 922 x 121 x 443 = 38054913820
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
922 : 1, 2, 461, 922
121 : 1, 11, 121
443 : 1, 443
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,922,121,443, is 1.
Now, the common factors can be found like this.
770:2x 5x 7x 11
922:2x 461
121:11x 11
443:443
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11 = 22
Therefore, the value for common factors is 22.
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 = 38054913820/(1x22)
LCM = 38054913820/22
LCM = 1729768810
Thus, we can understand that the LCM of 770,922,121,443 is 1729768810.
