Given numbers are 276,220,947,399
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 276,220,947,399 is 1911936180.
Find LCM of 276,220,947,399 with Prime Factorization
| 2 | 276, 220, 947, 399 |
| 2 | 138, 110, 947, 399 |
| 3 | 69, 55, 947, 399 |
| 23, 55, 947, 133 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 23 x 55 x 947 x 133 = 1911936180
Therefore, the lowest common multiple of 276,220,947,399 is 1911936180.
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.
276 x 220 x 947 x 399 = 22943234160
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.
276 : 1, 2, 3, 4, 6, 12, 23, 46, 69, 92, 138, 276
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
947 : 1, 947
399 : 1, 3, 7, 19, 21, 57, 133, 399
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 276,220,947,399, is 1.
Now, the common factors can be found like this.
276:2x 2x 3x 23
220:2x 2x 5x 11
947:947
399:3x 7x 19
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 3 = 12
Therefore, the value for common factors is 12.
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 = 22943234160/(1x12)
LCM = 22943234160/12
LCM = 1911936180
Thus, we can understand that the LCM of 276,220,947,399 is 1911936180.
