Find LCM of 340,299,989,520 with Prime Factorization
| 2 | 340, 299, 989, 520 |
| 2 | 170, 299, 989, 260 |
| 5 | 85, 299, 989, 130 |
| 13 | 17, 299, 989, 26 |
| 23 | 17, 23, 989, 2 |
| 17, 1, 43, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 23 x 17 x 1 x 43 x 2 = 8742760
Therefore, the lowest common multiple of 340,299,989,520 is 8742760.
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.
340 x 299 x 989 x 520 = 52281704800
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.
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
299 : 1, 13, 23, 299
989 : 1, 23, 43, 989
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 340,299,989,520, is 1.
Now, the common factors can be found like this.
340:2x 2x 5x 17
299:13x 23
989:23x 43
520:2x 2x 2x 5x 13
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 5x 13x 23 = 5980
Therefore, the value for common factors is 5980.
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 = 52281704800/(1x5980)
LCM = 52281704800/5980
LCM = 8742760
Thus, we can understand that the LCM of 340,299,989,520 is 8742760.
