Given numbers are 281,266,208,143,490
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 281,266,208,143,490 is 2992829840.
Find LCM of 281,266,208,143,490 with Prime Factorization
2 | 281, 266, 208, 143, 490 |
7 | 281, 133, 104, 143, 245 |
13 | 281, 19, 104, 143, 35 |
281, 19, 8, 11, 35 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 13 x 281 x 19 x 8 x 11 x 35 = 2992829840
Therefore, the lowest common multiple of 281,266,208,143,490 is 2992829840.
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.
281 x 266 x 208 x 143 x 490 = 1089390061760
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.
281 : 1, 281
266 : 1, 2, 7, 14, 19, 38, 133, 266
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
143 : 1, 11, 13, 143
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,266,208,143,490, is 1.
Now, the common factors can be found like this.
281:281
266:2x 7x 19
208:2x 2x 2x 2x 13
143:11x 13
490:2x 5x 7x 7
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 7x 13 = 364
Therefore, the value for common factors is 364.
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 = 1089390061760/(1x364)
LCM = 1089390061760/364
LCM = 2992829840
Thus, we can understand that the LCM of 281,266,208,143,490 is 2992829840.
