Given numbers are 770,229,385,685
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 770,229,385,685 is 24157210.
Find LCM of 770,229,385,685 with Prime Factorization
| 5 | 770, 229, 385, 685 |
| 7 | 154, 229, 77, 137 |
| 11 | 22, 229, 11, 137 |
| 2, 229, 1, 137 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 11 x 2 x 229 x 1 x 137 = 24157210
Therefore, the lowest common multiple of 770,229,385,685 is 24157210.
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 229 x 385 x 685 = 46502629250
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
229 : 1, 229
385 : 1, 5, 7, 11, 35, 55, 77, 385
685 : 1, 5, 137, 685
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,229,385,685, is 1.
Now, the common factors can be found like this.
770:2x 5x 7x 11
229:229
385:5x 7x 11
685:5x 137
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 7x 11 = 1925
Therefore, the value for common factors is 1925.
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 = 46502629250/(1x1925)
LCM = 46502629250/1925
LCM = 24157210
Thus, we can understand that the LCM of 770,229,385,685 is 24157210.
