Given numbers are 801,307,921,480
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 801,307,921,480 is 39345120.
Find LCM of 801,307,921,480 with Prime Factorization
| 3 | 801, 307, 921, 480 |
| 307 | 267, 307, 307, 160 |
| 267, 1, 1, 160 |
Multiply the prime numbers at the bottom and the left side.
3 x 307 x 267 x 1 x 1 x 160 = 39345120
Therefore, the lowest common multiple of 801,307,921,480 is 39345120.
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.
801 x 307 x 921 x 480 = 108710566560
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.
801 : 1, 3, 9, 89, 267, 801
307 : 1, 307
921 : 1, 3, 307, 921
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 801,307,921,480, is 1.
Now, the common factors can be found like this.
801:3x 3x 89
307:307
921:3x 307
480:2x 2x 2x 2x 2x 3x 5
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 307 = 2763
Therefore, the value for common factors is 2763.
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 = 108710566560/(1x2763)
LCM = 108710566560/2763
LCM = 39345120
Thus, we can understand that the LCM of 801,307,921,480 is 39345120.
