The LCM of 765,645,700,352,630 is 405266400.
Find LCM of 765,645,700,352,630 with Prime Factorization
| 2 | 765, 645, 700, 352, 630 |
| 2 | 765, 645, 350, 176, 315 |
| 3 | 765, 645, 175, 88, 315 |
| 3 | 255, 215, 175, 88, 105 |
| 5 | 85, 215, 175, 88, 35 |
| 7 | 17, 43, 7, 88, 35 |
| 17, 43, 1, 88, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 7 x 17 x 43 x 1 x 88 x 5 = 405266400
Therefore, the lowest common multiple of 765,645,700,352,630 is 405266400.
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 645 x 700 x 352 x 630 = 76595349600000
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
645 : 1, 3, 5, 15, 43, 129, 215, 645
700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700
352 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 176, 352
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 765,645,700,352,630, is 1.
Now, the common factors can be found like this.
765:3x 3x 5x 17
645:3x 5x 43
700:2x 2x 5x 5x 7
352:2x 2x 2x 2x 2x 11
630:2x 3x 3x 5x 7
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 3x 3x 3x 5x 5x 5x 7 = 189000
Therefore, the value for common factors is 189000.
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 = 76595349600000/(1x189000)
LCM = 76595349600000/189000
LCM = 405266400
Thus, we can understand that the LCM of 765,645,700,352,630 is 405266400.
