Given numbers are 210,280,851,907,902
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 210,280,851,907,902 is 292410305880.
Find LCM of 210,280,851,907,902 with Prime Factorization
| 2 | 210, 280, 851, 907, 902 |
| 5 | 105, 140, 851, 907, 451 |
| 7 | 21, 28, 851, 907, 451 |
| 3, 4, 851, 907, 451 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 3 x 4 x 851 x 907 x 451 = 292410305880
Therefore, the lowest common multiple of 210,280,851,907,902 is 292410305880.
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.
210 x 280 x 851 x 907 x 902 = 40937442823200
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.
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
851 : 1, 23, 37, 851
907 : 1, 907
902 : 1, 2, 11, 22, 41, 82, 451, 902
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 210,280,851,907,902, is 1.
Now, the common factors can be found like this.
210:2x 3x 5x 7
280:2x 2x 2x 5x 7
851:23x 37
907:907
902:2x 11x 41
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 5x 7 = 140
Therefore, the value for common factors is 140.
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 = 40937442823200/(1x140)
LCM = 40937442823200/140
LCM = 292410305880
Thus, we can understand that the LCM of 210,280,851,907,902 is 292410305880.
