The LCM of 552,285,456,947 is 49660680.
Find LCM of 552,285,456,947 with Prime Factorization
| 2 | 552, 285, 456, 947 |
| 2 | 276, 285, 228, 947 |
| 2 | 138, 285, 114, 947 |
| 3 | 69, 285, 57, 947 |
| 19 | 23, 95, 19, 947 |
| 23, 5, 1, 947 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 19 x 23 x 5 x 1 x 947 = 49660680
Therefore, the lowest common multiple of 552,285,456,947 is 49660680.
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.
552 x 285 x 456 x 947 = 67935810240
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.
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
285 : 1, 3, 5, 15, 19, 57, 95, 285
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
947 : 1, 947
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 552,285,456,947, is 1.
Now, the common factors can be found like this.
552:2x 2x 2x 3x 23
285:3x 5x 19
456:2x 2x 2x 3x 19
947:947
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 3x 3x 19 = 1368
Therefore, the value for common factors is 1368.
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 = 67935810240/(1x1368)
LCM = 67935810240/1368
LCM = 49660680
Thus, we can understand that the LCM of 552,285,456,947 is 49660680.
