Find LCM of 564,782,648,686,972 with Prime Factorization
| 2 | 564, 782, 648, 686, 972 |
| 2 | 282, 391, 324, 343, 486 |
| 3 | 141, 391, 162, 343, 243 |
| 3 | 47, 391, 54, 343, 81 |
| 3 | 47, 391, 18, 343, 27 |
| 3 | 47, 391, 6, 343, 9 |
| 47, 391, 2, 343, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 3 x 47 x 391 x 2 x 343 x 3 = 12253636584
Therefore, the lowest common multiple of 564,782,648,686,972 is 12253636584.
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 782 x 648 x 686 x 972 = 190568556154368
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
782 : 1, 2, 17, 23, 34, 46, 391, 782
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
686 : 1, 2, 7, 14, 49, 98, 343, 686
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 564,782,648,686,972, is 2.
Now, the common factors can be found like this.
564:2x 2x 3x 47
782:2x 17x 23
648:2x 2x 2x 3x 3x 3x 3
686:2x 7x 7x 7
972:2x 2x 3x 3x 3x 3x 3
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 2x 3x 3x 3x 3x 3 = 7776
Therefore, the value for common factors is 7776.
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 = 190568556154368/(2x7776)
LCM = 190568556154368/15552
LCM = 12253636584
Thus, we can understand that the LCM of 564,782,648,686,972 is 12253636584.
