The LCM of 326,436,403,680,765 is 43819818120.
Find LCM of 326,436,403,680,765 with Prime Factorization
| 2 | 326, 436, 403, 680, 765 |
| 2 | 163, 218, 403, 340, 765 |
| 5 | 163, 109, 403, 170, 765 |
| 17 | 163, 109, 403, 34, 153 |
| 163, 109, 403, 2, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 17 x 163 x 109 x 403 x 2 x 9 = 43819818120
Therefore, the lowest common multiple of 326,436,403,680,765 is 43819818120.
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.
326 x 436 x 403 x 680 x 765 = 29797476321600
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.
326 : 1, 2, 163, 326
436 : 1, 2, 4, 109, 218, 436
403 : 1, 13, 31, 403
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 326,436,403,680,765, is 1.
Now, the common factors can be found like this.
326:2x 163
436:2x 2x 109
403:13x 31
680:2x 2x 2x 5x 17
765:3x 3x 5x 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 2x 5x 17 = 680
Therefore, the value for common factors is 680.
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 = 29797476321600/(1x680)
LCM = 29797476321600/680
LCM = 43819818120
Thus, we can understand that the LCM of 326,436,403,680,765 is 43819818120.
