Given numbers are 775,698,290,685,245
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 775,698,290,685,245 is 105310523150.
Find LCM of 775,698,290,685,245 with Prime Factorization
| 2 | 775, 698, 290, 685, 245 |
| 5 | 775, 349, 145, 685, 245 |
| 155, 349, 29, 137, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 155 x 349 x 29 x 137 x 49 = 105310523150
Therefore, the lowest common multiple of 775,698,290,685,245 is 105310523150.
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.
775 x 698 x 290 x 685 x 245 = 26327630787500
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.
775 : 1, 5, 25, 31, 155, 775
698 : 1, 2, 349, 698
290 : 1, 2, 5, 10, 29, 58, 145, 290
685 : 1, 5, 137, 685
245 : 1, 5, 7, 35, 49, 245
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 775,698,290,685,245, is 1.
Now, the common factors can be found like this.
775:5x 5x 31
698:2x 349
290:2x 5x 29
685:5x 137
245:5x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 5 = 250
Therefore, the value for common factors is 250.
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 = 26327630787500/(1x250)
LCM = 26327630787500/250
LCM = 105310523150
Thus, we can understand that the LCM of 775,698,290,685,245 is 105310523150.
