The LCM of 805,456,865,736 is 254019360.
Find LCM of 805,456,865,736 with Prime Factorization
| 2 | 805, 456, 865, 736 |
| 2 | 805, 228, 865, 368 |
| 2 | 805, 114, 865, 184 |
| 5 | 805, 57, 865, 92 |
| 23 | 161, 57, 173, 92 |
| 7, 57, 173, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 23 x 7 x 57 x 173 x 4 = 254019360
Therefore, the lowest common multiple of 805,456,865,736 is 254019360.
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.
805 x 456 x 865 x 736 = 233697811200
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.
805 : 1, 5, 7, 23, 35, 115, 161, 805
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
865 : 1, 5, 173, 865
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 805,456,865,736, is 1.
Now, the common factors can be found like this.
805:5x 7x 23
456:2x 2x 2x 3x 19
865:5x 173
736:2x 2x 2x 2x 2x 23
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 5x 23 = 920
Therefore, the value for common factors is 920.
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 = 233697811200/(1x920)
LCM = 233697811200/920
LCM = 254019360
Thus, we can understand that the LCM of 805,456,865,736 is 254019360.
