Find LCM of 553,214,828,621 with Prime Factorization
| 2 | 553, 214, 828, 621 |
| 3 | 553, 107, 414, 621 |
| 3 | 553, 107, 138, 207 |
| 23 | 553, 107, 46, 69 |
| 553, 107, 2, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 23 x 553 x 107 x 2 x 3 = 146980764
Therefore, the lowest common multiple of 553,214,828,621 is 146980764.
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.
553 x 214 x 828 x 621 = 60850036296
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.
553 : 1, 7, 79, 553
214 : 1, 2, 107, 214
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 553,214,828,621, is 1.
Now, the common factors can be found like this.
553:7x 79
214:2x 107
828:2x 2x 3x 3x 23
621:3x 3x 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 3x 3x 23 = 414
Therefore, the value for common factors is 414.
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 = 60850036296/(1x414)
LCM = 60850036296/414
LCM = 146980764
Thus, we can understand that the LCM of 553,214,828,621 is 146980764.
