Find LCM of 861,615,716,812,536 with Prime Factorization
| 2 | 861, 615, 716, 812, 536 |
| 2 | 861, 615, 358, 406, 268 |
| 3 | 861, 615, 179, 203, 134 |
| 7 | 287, 205, 179, 203, 134 |
| 41 | 41, 205, 179, 29, 134 |
| 1, 5, 179, 29, 134 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 41 x 1 x 5 x 179 x 29 x 134 = 11978128680
Therefore, the lowest common multiple of 861,615,716,812,536 is 11978128680.
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.
861 x 615 x 716 x 812 x 536 = 165010700695680
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.
861 : 1, 3, 7, 21, 41, 123, 287, 861
615 : 1, 3, 5, 15, 41, 123, 205, 615
716 : 1, 2, 4, 179, 358, 716
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
536 : 1, 2, 4, 8, 67, 134, 268, 536
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,615,716,812,536, is 1.
Now, the common factors can be found like this.
861:3x 7x 41
615:3x 5x 41
716:2x 2x 179
812:2x 2x 7x 29
536:2x 2x 2x 67
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 3x 7x 41 = 13776
Therefore, the value for common factors is 13776.
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 = 165010700695680/(1x13776)
LCM = 165010700695680/13776
LCM = 11978128680
Thus, we can understand that the LCM of 861,615,716,812,536 is 11978128680.
