Find LCM of 648,142,566,756 with Prime Factorization
| 2 | 648, 142, 566, 756 |
| 2 | 324, 71, 283, 378 |
| 3 | 162, 71, 283, 189 |
| 3 | 54, 71, 283, 63 |
| 3 | 18, 71, 283, 21 |
| 6, 71, 283, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 6 x 71 x 283 x 7 = 91141848
Therefore, the lowest common multiple of 648,142,566,756 is 91141848.
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.
648 x 142 x 566 x 756 = 39373278336
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.
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
142 : 1, 2, 71, 142
566 : 1, 2, 283, 566
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 648,142,566,756, is 2.
Now, the common factors can be found like this.
648:2x 2x 2x 3x 3x 3x 3
142:2x 71
566:2x 283
756:2x 2x 3x 3x 3x 7
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 3 = 216
Therefore, the value for common factors is 216.
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 = 39373278336/(2x216)
LCM = 39373278336/432
LCM = 91141848
Thus, we can understand that the LCM of 648,142,566,756 is 91141848.
