Given numbers are 812,700,560,892
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 812,700,560,892 is 18107600.
Find LCM of 812,700,560,892 with Prime Factorization
| 2 | 812, 700, 560, 892 |
| 2 | 406, 350, 280, 446 |
| 5 | 203, 175, 140, 223 |
| 7 | 203, 35, 28, 223 |
| 29, 5, 4, 223 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 29 x 5 x 4 x 223 = 18107600
Therefore, the lowest common multiple of 812,700,560,892 is 18107600.
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.
812 x 700 x 560 x 892 = 283927168000
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.
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
892 : 1, 2, 4, 223, 446, 892
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 812,700,560,892, is 4.
Now, the common factors can be found like this.
812:2x 2x 7x 29
700:2x 2x 5x 5x 7
560:2x 2x 2x 2x 5x 7
892:2x 2x 223
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 5x 7x 7 = 3920
Therefore, the value for common factors is 3920.
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 = 283927168000/(4x3920)
LCM = 283927168000/15680
LCM = 18107600
Thus, we can understand that the LCM of 812,700,560,892 is 18107600.
