Given numbers are 380,802,100,276
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 380,802,100,276 is 52571100.
Find LCM of 380,802,100,276 with Prime Factorization
| 2 | 380, 802, 100, 276 |
| 2 | 190, 401, 50, 138 |
| 5 | 95, 401, 25, 69 |
| 19, 401, 5, 69 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 19 x 401 x 5 x 69 = 52571100
Therefore, the lowest common multiple of 380,802,100,276 is 52571100.
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.
380 x 802 x 100 x 276 = 8411376000
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.
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
802 : 1, 2, 401, 802
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
276 : 1, 2, 3, 4, 6, 12, 23, 46, 69, 92, 138, 276
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 380,802,100,276, is 2.
Now, the common factors can be found like this.
380:2x 2x 5x 19
802:2x 401
100:2x 2x 5x 5
276:2x 2x 3x 23
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 2x 2x 5 = 80
Therefore, the value for common factors is 80.
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 = 8411376000/(2x80)
LCM = 8411376000/160
LCM = 52571100
Thus, we can understand that the LCM of 380,802,100,276 is 52571100.
