Find LCM of 812,716,517,748,154 with Prime Factorization
| 2 | 812, 716, 517, 748, 154 |
| 2 | 406, 358, 517, 374, 77 |
| 7 | 203, 179, 517, 187, 77 |
| 11 | 29, 179, 517, 187, 11 |
| 29, 179, 47, 17, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 11 x 29 x 179 x 47 x 17 x 1 = 1277463572
Therefore, the lowest common multiple of 812,716,517,748,154 is 1277463572.
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.
812 x 716 x 517 x 748 x 154 = 34624372655488
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.
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
716 : 1, 2, 4, 179, 358, 716
517 : 1, 11, 47, 517
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
154 : 1, 2, 7, 11, 14, 22, 77, 154
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 812,716,517,748,154, is 1.
Now, the common factors can be found like this.
812:2x 2x 7x 29
716:2x 2x 179
517:11x 47
748:2x 2x 11x 17
154:2x 7x 11
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 2x 2x 7x 11x 11 = 27104
Therefore, the value for common factors is 27104.
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 = 34624372655488/(1x27104)
LCM = 34624372655488/27104
LCM = 1277463572
Thus, we can understand that the LCM of 812,716,517,748,154 is 1277463572.
