Find LCM of 865,396,465,462 with Prime Factorization
| 2 | 865, 396, 465, 462 |
| 3 | 865, 198, 465, 231 |
| 5 | 865, 66, 155, 77 |
| 11 | 173, 66, 31, 77 |
| 173, 6, 31, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 173 x 6 x 31 x 7 = 74331180
Therefore, the lowest common multiple of 865,396,465,462 is 74331180.
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.
865 x 396 x 465 x 462 = 73587868200
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.
865 : 1, 5, 173, 865
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
465 : 1, 3, 5, 15, 31, 93, 155, 465
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 865,396,465,462, is 1.
Now, the common factors can be found like this.
865:5x 173
396:2x 2x 3x 3x 11
465:3x 5x 31
462:2x 3x 7x 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 3x 3x 5x 11 = 990
Therefore, the value for common factors is 990.
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 = 73587868200/(1x990)
LCM = 73587868200/990
LCM = 74331180
Thus, we can understand that the LCM of 865,396,465,462 is 74331180.
