Find LCM of 730,186,646,961,255 with Prime Factorization
| 2 | 730, 186, 646, 961, 255 |
| 3 | 365, 93, 323, 961, 255 |
| 5 | 365, 31, 323, 961, 85 |
| 17 | 73, 31, 323, 961, 17 |
| 31 | 73, 31, 19, 961, 1 |
| 73, 1, 19, 31, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 17 x 31 x 73 x 1 x 19 x 31 x 1 = 679782570
Therefore, the lowest common multiple of 730,186,646,961,255 is 679782570.
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.
730 x 186 x 646 x 961 x 255 = 21494724863400
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.
730 : 1, 2, 5, 10, 73, 146, 365, 730
186 : 1, 2, 3, 6, 31, 62, 93, 186
646 : 1, 2, 17, 19, 34, 38, 323, 646
961 : 1, 31, 961
255 : 1, 3, 5, 15, 17, 51, 85, 255
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 730,186,646,961,255, is 1.
Now, the common factors can be found like this.
730:2x 5x 73
186:2x 3x 31
646:2x 17x 19
961:31x 31
255:3x 5x 17
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 17x 31 = 31620
Therefore, the value for common factors is 31620.
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 = 21494724863400/(1x31620)
LCM = 21494724863400/31620
LCM = 679782570
Thus, we can understand that the LCM of 730,186,646,961,255 is 679782570.
