Find LCM of 187,803,780,993,812 with Prime Factorization
| 2 | 187, 803, 780, 993, 812 |
| 2 | 187, 803, 390, 993, 406 |
| 3 | 187, 803, 195, 993, 203 |
| 11 | 187, 803, 65, 331, 203 |
| 17, 73, 65, 331, 203 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 17 x 73 x 65 x 331 x 203 = 715456281540
Therefore, the lowest common multiple of 187,803,780,993,812 is 715456281540.
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.
187 x 803 x 780 x 993 x 812 = 94440229163280
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.
187 : 1, 11, 17, 187
803 : 1, 11, 73, 803
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
993 : 1, 3, 331, 993
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 187,803,780,993,812, is 1.
Now, the common factors can be found like this.
187:11x 17
803:11x 73
780:2x 2x 3x 5x 13
993:3x 331
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 3x 11 = 132
Therefore, the value for common factors is 132.
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 = 94440229163280/(1x132)
LCM = 94440229163280/132
LCM = 715456281540
Thus, we can understand that the LCM of 187,803,780,993,812 is 715456281540.
