Given numbers are 849,902,812,400
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 849,902,812,400 is 31091398800.
Find LCM of 849,902,812,400 with Prime Factorization
| 2 | 849, 902, 812, 400 |
| 2 | 849, 451, 406, 200 |
| 849, 451, 203, 100 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 849 x 451 x 203 x 100 = 31091398800
Therefore, the lowest common multiple of 849,902,812,400 is 31091398800.
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.
849 x 902 x 812 x 400 = 248731190400
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.
849 : 1, 3, 283, 849
902 : 1, 2, 11, 22, 41, 82, 451, 902
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 849,902,812,400, is 1.
Now, the common factors can be found like this.
849:3x 283
902:2x 11x 41
812:2x 2x 7x 29
400:2x 2x 2x 2x 5x 5
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 2 = 8
Therefore, the value for common factors is 8.
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 = 248731190400/(1x8)
LCM = 248731190400/8
LCM = 31091398800
Thus, we can understand that the LCM of 849,902,812,400 is 31091398800.
