Given numbers are 835,686,245,261,700
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 835,686,245,261,700 is 1495034100.
Find LCM of 835,686,245,261,700 with Prime Factorization
| 2 | 835, 686, 245, 261, 700 |
| 5 | 835, 343, 245, 261, 350 |
| 7 | 167, 343, 49, 261, 70 |
| 7 | 167, 7, 49, 261, 10 |
| 167, 1, 7, 261, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 7 x 167 x 1 x 7 x 261 x 10 = 1495034100
Therefore, the lowest common multiple of 835,686,245,261,700 is 1495034100.
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.
835 x 686 x 245 x 261 x 700 = 25639834815000
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.
835 : 1, 5, 167, 835
686 : 1, 2, 7, 14, 49, 98, 343, 686
245 : 1, 5, 7, 35, 49, 245
261 : 1, 3, 9, 29, 87, 261
700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 835,686,245,261,700, is 1.
Now, the common factors can be found like this.
835:5x 167
686:2x 7x 7x 7
245:5x 7x 7
261:3x 3x 29
700:2x 2x 5x 5x 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 7x 7x 7 = 17150
Therefore, the value for common factors is 17150.
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 = 25639834815000/(1x17150)
LCM = 25639834815000/17150
LCM = 1495034100
Thus, we can understand that the LCM of 835,686,245,261,700 is 1495034100.
