The LCM of 564,654,972,621 is 114529788.
Find LCM of 564,654,972,621 with Prime Factorization
| 2 | 564, 654, 972, 621 |
| 2 | 282, 327, 486, 621 |
| 3 | 141, 327, 243, 621 |
| 3 | 47, 109, 81, 207 |
| 3 | 47, 109, 27, 69 |
| 47, 109, 9, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 47 x 109 x 9 x 23 = 114529788
Therefore, the lowest common multiple of 564,654,972,621 is 114529788.
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.
564 x 654 x 972 x 621 = 222645907872
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.
564 : 1, 2, 3, 4, 6, 12, 47, 94, 141, 188, 282, 564
654 : 1, 2, 3, 6, 109, 218, 327, 654
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
621 : 1, 3, 9, 23, 27, 69, 207, 621
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 564,654,972,621, is 3.
Now, the common factors can be found like this.
564:2x 2x 3x 47
654:2x 3x 109
972:2x 2x 3x 3x 3x 3x 3
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 2x 2x 3x 3x 3x 3 = 648
Therefore, the value for common factors is 648.
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 = 222645907872/(3x648)
LCM = 222645907872/1944
LCM = 114529788
Thus, we can understand that the LCM of 564,654,972,621 is 114529788.
