Given numbers are 720,676,300,173
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 720,676,300,173 is 105253200.
Find LCM of 720,676,300,173 with Prime Factorization
| 2 | 720, 676, 300, 173 |
| 2 | 360, 338, 150, 173 |
| 3 | 180, 169, 75, 173 |
| 5 | 60, 169, 25, 173 |
| 12, 169, 5, 173 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 12 x 169 x 5 x 173 = 105253200
Therefore, the lowest common multiple of 720,676,300,173 is 105253200.
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.
720 x 676 x 300 x 173 = 25260768000
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.
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
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
300 : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, 300
173 : 1, 173
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,676,300,173, is 1.
Now, the common factors can be found like this.
720:2x 2x 2x 2x 3x 3x 5
676:2x 2x 13x 13
300:2x 2x 3x 5x 5
173:173
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 2x 3x 5 = 240
Therefore, the value for common factors is 240.
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 = 25260768000/(1x240)
LCM = 25260768000/240
LCM = 105253200
Thus, we can understand that the LCM of 720,676,300,173 is 105253200.
