Find LCM of 865,154,621,306,374 with Prime Factorization
| 2 | 865, 154, 621, 306, 374 |
| 3 | 865, 77, 621, 153, 187 |
| 3 | 865, 77, 207, 51, 187 |
| 11 | 865, 77, 69, 17, 187 |
| 17 | 865, 7, 69, 17, 17 |
| 865, 7, 69, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 17 x 865 x 7 x 69 x 1 x 1 = 1406297970
Therefore, the lowest common multiple of 865,154,621,306,374 is 1406297970.
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 154 x 621 x 306 x 374 = 9467197934040
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
154 : 1, 2, 7, 11, 14, 22, 77, 154
621 : 1, 3, 9, 23, 27, 69, 207, 621
306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306
374 : 1, 2, 11, 17, 22, 34, 187, 374
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 865,154,621,306,374, is 1.
Now, the common factors can be found like this.
865:5x 173
154:2x 7x 11
621:3x 3x 3x 23
306:2x 3x 3x 17
374:2x 11x 17
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 3x 3x 11x 17 = 6732
Therefore, the value for common factors is 6732.
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 = 9467197934040/(1x6732)
LCM = 9467197934040/6732
LCM = 1406297970
Thus, we can understand that the LCM of 865,154,621,306,374 is 1406297970.
