Find LCM of 456,528,844,642 with Prime Factorization
| 2 | 456, 528, 844, 642 |
| 2 | 228, 264, 422, 321 |
| 2 | 114, 132, 211, 321 |
| 3 | 57, 66, 211, 321 |
| 19, 22, 211, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 19 x 22 x 211 x 107 = 226492464
Therefore, the lowest common multiple of 456,528,844,642 is 226492464.
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.
456 x 528 x 844 x 642 = 130459659264
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.
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
528 : 1, 2, 3, 4, 6, 8, 11, 12, 16, 22, 24, 33, 44, 48, 66, 88, 132, 176, 264, 528
844 : 1, 2, 4, 211, 422, 844
642 : 1, 2, 3, 6, 107, 214, 321, 642
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 456,528,844,642, is 2.
Now, the common factors can be found like this.
456:2x 2x 2x 3x 19
528:2x 2x 2x 2x 3x 11
844:2x 2x 211
642:2x 3x 107
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 3 = 288
Therefore, the value for common factors is 288.
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 = 130459659264/(2x288)
LCM = 130459659264/576
LCM = 226492464
Thus, we can understand that the LCM of 456,528,844,642 is 226492464.
