Given numbers are 248,391,930,763,321
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 248,391,930,763,321 is 118748467320.
Find LCM of 248,391,930,763,321 with Prime Factorization
| 2 | 248, 391, 930, 763, 321 |
| 3 | 124, 391, 465, 763, 321 |
| 31 | 124, 391, 155, 763, 107 |
| 4, 391, 5, 763, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 31 x 4 x 391 x 5 x 763 x 107 = 118748467320
Therefore, the lowest common multiple of 248,391,930,763,321 is 118748467320.
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.
248 x 391 x 930 x 763 x 321 = 22087214921520
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.
248 : 1, 2, 4, 8, 31, 62, 124, 248
391 : 1, 17, 23, 391
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
763 : 1, 7, 109, 763
321 : 1, 3, 107, 321
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 248,391,930,763,321, is 1.
Now, the common factors can be found like this.
248:2x 2x 2x 31
391:17x 23
930:2x 3x 5x 31
763:7x 109
321:3x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 31 = 186
Therefore, the value for common factors is 186.
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 = 22087214921520/(1x186)
LCM = 22087214921520/186
LCM = 118748467320
Thus, we can understand that the LCM of 248,391,930,763,321 is 118748467320.
