Find LCM of 765,805,173,987,534 with Prime Factorization
| 3 | 765, 805, 173, 987, 534 |
| 5 | 255, 805, 173, 329, 178 |
| 7 | 51, 161, 173, 329, 178 |
| 51, 23, 173, 47, 178 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 51 x 23 x 173 x 47 x 178 = 178258921470
Therefore, the lowest common multiple of 765,805,173,987,534 is 178258921470.
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.
765 x 805 x 173 x 987 x 534 = 56151560263050
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.
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
805 : 1, 5, 7, 23, 35, 115, 161, 805
173 : 1, 173
987 : 1, 3, 7, 21, 47, 141, 329, 987
534 : 1, 2, 3, 6, 89, 178, 267, 534
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 765,805,173,987,534, is 1.
Now, the common factors can be found like this.
765:3x 3x 5x 17
805:5x 7x 23
173:173
987:3x 7x 47
534:2x 3x 89
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 7 = 315
Therefore, the value for common factors is 315.
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 = 56151560263050/(1x315)
LCM = 56151560263050/315
LCM = 178258921470
Thus, we can understand that the LCM of 765,805,173,987,534 is 178258921470.
