Given numbers are 730,306,686,100,851
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 730,306,686,100,851 is 326015291700.
Find LCM of 730,306,686,100,851 with Prime Factorization
| 2 | 730, 306, 686, 100, 851 |
| 5 | 365, 153, 343, 50, 851 |
| 73, 153, 343, 10, 851 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 73 x 153 x 343 x 10 x 851 = 326015291700
Therefore, the lowest common multiple of 730,306,686,100,851 is 326015291700.
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.
730 x 306 x 686 x 100 x 851 = 13040611668000
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.
730 : 1, 2, 5, 10, 73, 146, 365, 730
306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306
686 : 1, 2, 7, 14, 49, 98, 343, 686
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
851 : 1, 23, 37, 851
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 730,306,686,100,851, is 1.
Now, the common factors can be found like this.
730:2x 5x 73
306:2x 3x 3x 17
686:2x 7x 7x 7
100:2x 2x 5x 5
851:23x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 5 = 40
Therefore, the value for common factors is 40.
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 = 13040611668000/(1x40)
LCM = 13040611668000/40
LCM = 326015291700
Thus, we can understand that the LCM of 730,306,686,100,851 is 326015291700.
