Find LCM of 778,645,686,630,812 with Prime Factorization
2 | 778, 645, 686, 630, 812 |
3 | 389, 645, 343, 315, 406 |
5 | 389, 215, 343, 105, 406 |
7 | 389, 43, 343, 21, 406 |
389, 43, 49, 3, 58 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 389 x 43 x 49 x 3 x 58 = 29949024420
Therefore, the lowest common multiple of 778,645,686,630,812 is 29949024420.
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.
778 x 645 x 686 x 630 x 812 = 176100263589600
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.
778 : 1, 2, 389, 778
645 : 1, 3, 5, 15, 43, 129, 215, 645
686 : 1, 2, 7, 14, 49, 98, 343, 686
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
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,645,686,630,812, is 1.
Now, the common factors can be found like this.
778:2x 389
645:3x 5x 43
686:2x 7x 7x 7
630:2x 3x 3x 5x 7
812:2x 2x 7x 29
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 5x 7x 7 = 5880
Therefore, the value for common factors is 5880.
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 = 176100263589600/(1x5880)
LCM = 176100263589600/5880
LCM = 29949024420
Thus, we can understand that the LCM of 778,645,686,630,812 is 29949024420.
