Find LCM of 945,842,882,757 with Prime Factorization
| 2 | 945, 842, 882, 757 |
| 3 | 945, 421, 441, 757 |
| 3 | 315, 421, 147, 757 |
| 7 | 105, 421, 49, 757 |
| 15, 421, 7, 757 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 15 x 421 x 7 x 757 = 4216361310
Therefore, the lowest common multiple of 945,842,882,757 is 4216361310.
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.
945 x 842 x 882 x 757 = 531261525060
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.
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
842 : 1, 2, 421, 842
882 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 49, 63, 98, 126, 147, 294, 441, 882
757 : 1, 757
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 945,842,882,757, is 1.
Now, the common factors can be found like this.
945:3x 3x 3x 5x 7
842:2x 421
882:2x 3x 3x 7x 7
757:757
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 7 = 126
Therefore, the value for common factors is 126.
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 = 531261525060/(1x126)
LCM = 531261525060/126
LCM = 4216361310
Thus, we can understand that the LCM of 945,842,882,757 is 4216361310.
