Find LCM of 641,930,165,148,474 with Prime Factorization
| 2 | 641, 930, 165, 148, 474 |
| 3 | 641, 465, 165, 74, 237 |
| 5 | 641, 155, 55, 74, 79 |
| 641, 31, 11, 74, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 641 x 31 x 11 x 74 x 79 = 38334735780
Therefore, the lowest common multiple of 641,930,165,148,474 is 38334735780.
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.
641 x 930 x 165 x 148 x 474 = 6900252440400
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.
641 : 1, 641
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
165 : 1, 3, 5, 11, 15, 33, 55, 165
148 : 1, 2, 4, 37, 74, 148
474 : 1, 2, 3, 6, 79, 158, 237, 474
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,930,165,148,474, is 1.
Now, the common factors can be found like this.
641:641
930:2x 3x 5x 31
165:3x 5x 11
148:2x 2x 37
474:2x 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 3x 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 6900252440400/(1x180)
LCM = 6900252440400/180
LCM = 38334735780
Thus, we can understand that the LCM of 641,930,165,148,474 is 38334735780.
