Given numbers are 281,380,532,105
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 281,380,532,105 is 2242380.
Find LCM of 281,380,532,105 with Prime Factorization
2 | 281, 380, 532, 105 |
2 | 281, 190, 266, 105 |
5 | 281, 95, 133, 105 |
7 | 281, 19, 133, 21 |
19 | 281, 19, 19, 3 |
281, 1, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 19 x 281 x 1 x 1 x 3 = 2242380
Therefore, the lowest common multiple of 281,380,532,105 is 2242380.
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 380 x 532 x 105 = 5964730800
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
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532
105 : 1, 3, 5, 7, 15, 21, 35, 105
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,380,532,105, is 1.
Now, the common factors can be found like this.
281:281
380:2x 2x 5x 19
532:2x 2x 7x 19
105:3x 5x 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 5x 7x 19 = 2660
Therefore, the value for common factors is 2660.
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 = 5964730800/(1x2660)
LCM = 5964730800/2660
LCM = 2242380
Thus, we can understand that the LCM of 281,380,532,105 is 2242380.
