Find LCM of 639,816,552,919,919 with Prime Factorization
| 2 | 639, 816, 552, 919, 919 |
| 2 | 639, 408, 276, 919, 919 |
| 2 | 639, 204, 138, 919, 919 |
| 3 | 639, 102, 69, 919, 919 |
| 919 | 213, 34, 23, 919, 919 |
| 213, 34, 23, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 919 x 213 x 34 x 23 x 1 x 1 = 3673779696
Therefore, the lowest common multiple of 639,816,552,919,919 is 3673779696.
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.
639 x 816 x 552 x 919 x 919 = 243086654924928
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.
639 : 1, 3, 9, 71, 213, 639
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
919 : 1, 919
919 : 1, 919
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,816,552,919,919, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
816:2x 2x 2x 2x 3x 17
552:2x 2x 2x 3x 23
919:919
919:919
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 919 = 66168
Therefore, the value for common factors is 66168.
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 = 243086654924928/(1x66168)
LCM = 243086654924928/66168
LCM = 3673779696
Thus, we can understand that the LCM of 639,816,552,919,919 is 3673779696.
