The LCM of 930,153,560,931 is 353258640.
Find LCM of 930,153,560,931 with Prime Factorization
| 2 | 930, 153, 560, 931 |
| 3 | 465, 153, 280, 931 |
| 5 | 155, 51, 280, 931 |
| 7 | 31, 51, 56, 931 |
| 31, 51, 8, 133 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 31 x 51 x 8 x 133 = 353258640
Therefore, the lowest common multiple of 930,153,560,931 is 353258640.
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 153 x 560 x 931 = 74184314400
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
153 : 1, 3, 9, 17, 51, 153
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
931 : 1, 7, 19, 49, 133, 931
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 930,153,560,931, is 1.
Now, the common factors can be found like this.
930:2x 3x 5x 31
153:3x 3x 17
560:2x 2x 2x 2x 5x 7
931:7x 7x 19
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 5x 7 = 210
Therefore, the value for common factors is 210.
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 = 74184314400/(1x210)
LCM = 74184314400/210
LCM = 353258640
Thus, we can understand that the LCM of 930,153,560,931 is 353258640.
