Given numbers are 251,140,275,385
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 251,140,275,385 is 1932700.
Find LCM of 251,140,275,385 with Prime Factorization
| 5 | 251, 140, 275, 385 |
| 7 | 251, 28, 55, 77 |
| 11 | 251, 4, 55, 11 |
| 251, 4, 5, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 11 x 251 x 4 x 5 x 1 = 1932700
Therefore, the lowest common multiple of 251,140,275,385 is 1932700.
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.
251 x 140 x 275 x 385 = 3720447500
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.
251 : 1, 251
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
275 : 1, 5, 11, 25, 55, 275
385 : 1, 5, 7, 11, 35, 55, 77, 385
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 251,140,275,385, is 1.
Now, the common factors can be found like this.
251:251
140:2x 2x 5x 7
275:5x 5x 11
385:5x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 7x 11 = 1925
Therefore, the value for common factors is 1925.
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 = 3720447500/(1x1925)
LCM = 3720447500/1925
LCM = 1932700
Thus, we can understand that the LCM of 251,140,275,385 is 1932700.
