Find LCM of 616,123,812,756,605 with Prime Factorization
| 2 | 616, 123, 812, 756, 605 |
| 2 | 308, 123, 406, 378, 605 |
| 3 | 154, 123, 203, 189, 605 |
| 7 | 154, 41, 203, 63, 605 |
| 11 | 22, 41, 29, 9, 605 |
| 2, 41, 29, 9, 55 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 11 x 2 x 41 x 29 x 9 x 55 = 1087649640
Therefore, the lowest common multiple of 616,123,812,756,605 is 1087649640.
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.
616 x 123 x 812 x 756 x 605 = 28139671486080
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.
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
123 : 1, 3, 41, 123
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
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
605 : 1, 5, 11, 55, 121, 605
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 616,123,812,756,605, is 1.
Now, the common factors can be found like this.
616:2x 2x 2x 7x 11
123:3x 41
812:2x 2x 7x 29
756:2x 2x 3x 3x 3x 7
605:5x 11x 11
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 3x 7x 7x 11 = 25872
Therefore, the value for common factors is 25872.
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 = 28139671486080/(1x25872)
LCM = 28139671486080/25872
LCM = 1087649640
Thus, we can understand that the LCM of 616,123,812,756,605 is 1087649640.
