The LCM of 513,472,639,836 is 189108216.
Find LCM of 513,472,639,836 with Prime Factorization
| 2 | 513, 472, 639, 836 |
| 2 | 513, 236, 639, 418 |
| 3 | 513, 118, 639, 209 |
| 3 | 171, 118, 213, 209 |
| 19 | 57, 118, 71, 209 |
| 3, 118, 71, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 19 x 3 x 118 x 71 x 11 = 189108216
Therefore, the lowest common multiple of 513,472,639,836 is 189108216.
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.
513 x 472 x 639 x 836 = 129350019744
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.
513 : 1, 3, 9, 19, 27, 57, 171, 513
472 : 1, 2, 4, 8, 59, 118, 236, 472
639 : 1, 3, 9, 71, 213, 639
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 513,472,639,836, is 1.
Now, the common factors can be found like this.
513:3x 3x 3x 19
472:2x 2x 2x 59
639:3x 3x 71
836:2x 2x 11x 19
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 3x 3x 19 = 684
Therefore, the value for common factors is 684.
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 = 129350019744/(1x684)
LCM = 129350019744/684
LCM = 189108216
Thus, we can understand that the LCM of 513,472,639,836 is 189108216.
