Find LCM of 741,180,171,646,948 with Prime Factorization
| 2 | 741, 180, 171, 646, 948 |
| 2 | 741, 90, 171, 323, 474 |
| 3 | 741, 45, 171, 323, 237 |
| 3 | 247, 15, 57, 323, 79 |
| 19 | 247, 5, 19, 323, 79 |
| 13, 5, 1, 17, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 19 x 13 x 5 x 1 x 17 x 79 = 59709780
Therefore, the lowest common multiple of 741,180,171,646,948 is 59709780.
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.
741 x 180 x 171 x 646 x 948 = 13967789415840
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.
741 : 1, 3, 13, 19, 39, 57, 247, 741
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
171 : 1, 3, 9, 19, 57, 171
646 : 1, 2, 17, 19, 34, 38, 323, 646
948 : 1, 2, 3, 4, 6, 12, 79, 158, 237, 316, 474, 948
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 741,180,171,646,948, is 1.
Now, the common factors can be found like this.
741:3x 13x 19
180:2x 2x 3x 3x 5
171:3x 3x 19
646:2x 17x 19
948:2x 2x 3x 79
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 3x 3x 19x 19 = 233928
Therefore, the value for common factors is 233928.
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 = 13967789415840/(1x233928)
LCM = 13967789415840/233928
LCM = 59709780
Thus, we can understand that the LCM of 741,180,171,646,948 is 59709780.
