Given numbers are 845,210,720,754
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 845,210,720,754 is 24701040.
Find LCM of 845,210,720,754 with Prime Factorization
| 2 | 845, 210, 720, 754 |
| 3 | 845, 105, 360, 377 |
| 5 | 845, 35, 120, 377 |
| 13 | 169, 7, 24, 377 |
| 13, 7, 24, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 13 x 7 x 24 x 29 = 24701040
Therefore, the lowest common multiple of 845,210,720,754 is 24701040.
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.
845 x 210 x 720 x 754 = 96334056000
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.
845 : 1, 5, 13, 65, 169, 845
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
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
754 : 1, 2, 13, 26, 29, 58, 377, 754
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,210,720,754, is 1.
Now, the common factors can be found like this.
845:5x 13x 13
210:2x 3x 5x 7
720:2x 2x 2x 2x 3x 3x 5
754:2x 13x 29
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 3x 5x 5x 13 = 3900
Therefore, the value for common factors is 3900.
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 = 96334056000/(1x3900)
LCM = 96334056000/3900
LCM = 24701040
Thus, we can understand that the LCM of 845,210,720,754 is 24701040.
