Given numbers are 763,457,867,980,686
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 763,457,867,980,686 is 296268795060.
Find LCM of 763,457,867,980,686 with Prime Factorization
| 2 | 763, 457, 867, 980, 686 |
| 7 | 763, 457, 867, 490, 343 |
| 7 | 109, 457, 867, 70, 49 |
| 109, 457, 867, 10, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 7 x 109 x 457 x 867 x 10 x 7 = 296268795060
Therefore, the lowest common multiple of 763,457,867,980,686 is 296268795060.
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.
763 x 457 x 867 x 980 x 686 = 203240393411160
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.
763 : 1, 7, 109, 763
457 : 1, 457
867 : 1, 3, 17, 51, 289, 867
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
686 : 1, 2, 7, 14, 49, 98, 343, 686
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 763,457,867,980,686, is 1.
Now, the common factors can be found like this.
763:7x 109
457:457
867:3x 17x 17
980:2x 2x 5x 7x 7
686:2x 7x 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 7x 7x 7 = 686
Therefore, the value for common factors is 686.
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 = 203240393411160/(1x686)
LCM = 203240393411160/686
LCM = 296268795060
Thus, we can understand that the LCM of 763,457,867,980,686 is 296268795060.
