Given numbers are 930,830,390,668
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 930,830,390,668 is 335158980.
Find LCM of 930,830,390,668 with Prime Factorization
| 2 | 930, 830, 390, 668 |
| 3 | 465, 415, 195, 334 |
| 5 | 155, 415, 65, 334 |
| 31, 83, 13, 334 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 31 x 83 x 13 x 334 = 335158980
Therefore, the lowest common multiple of 930,830,390,668 is 335158980.
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.
930 x 830 x 390 x 668 = 201095388000
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.
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
830 : 1, 2, 5, 10, 83, 166, 415, 830
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
668 : 1, 2, 4, 167, 334, 668
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 930,830,390,668, is 2.
Now, the common factors can be found like this.
930:2x 3x 5x 31
830:2x 5x 83
390:2x 3x 5x 13
668:2x 2x 167
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 5x 5 = 300
Therefore, the value for common factors is 300.
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 = 201095388000/(2x300)
LCM = 201095388000/600
LCM = 335158980
Thus, we can understand that the LCM of 930,830,390,668 is 335158980.
