Given numbers are 673,720,315,457
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 673,720,315,457 is 1550107440.
Find LCM of 673,720,315,457 with Prime Factorization
3 | 673, 720, 315, 457 |
3 | 673, 240, 105, 457 |
5 | 673, 80, 35, 457 |
673, 16, 7, 457 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 673 x 16 x 7 x 457 = 1550107440
Therefore, the lowest common multiple of 673,720,315,457 is 1550107440.
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.
673 x 720 x 315 x 457 = 69754834800
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.
673 : 1, 673
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
457 : 1, 457
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 673,720,315,457, is 1.
Now, the common factors can be found like this.
673:673
720:2x 2x 2x 2x 3x 3x 5
315:3x 3x 5x 7
457:457
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5 = 45
Therefore, the value for common factors is 45.
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 = 69754834800/(1x45)
LCM = 69754834800/45
LCM = 1550107440
Thus, we can understand that the LCM of 673,720,315,457 is 1550107440.
