Find LCM of 148,765,431,668,990 with Prime Factorization
| 2 | 148, 765, 431, 668, 990 |
| 2 | 74, 765, 431, 334, 495 |
| 3 | 37, 765, 431, 167, 495 |
| 3 | 37, 255, 431, 167, 165 |
| 5 | 37, 85, 431, 167, 55 |
| 37, 17, 431, 167, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 37 x 17 x 431 x 167 x 11 = 89641595340
Therefore, the lowest common multiple of 148,765,431,668,990 is 89641595340.
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.
148 x 765 x 431 x 668 x 990 = 32270974322400
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.
148 : 1, 2, 4, 37, 74, 148
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
431 : 1, 431
668 : 1, 2, 4, 167, 334, 668
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 148,765,431,668,990, is 1.
Now, the common factors can be found like this.
148:2x 2x 37
765:3x 3x 5x 17
431:431
668:2x 2x 167
990:2x 3x 3x 5x 11
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 2x 3x 3x 5 = 360
Therefore, the value for common factors is 360.
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 = 32270974322400/(1x360)
LCM = 32270974322400/360
LCM = 89641595340
Thus, we can understand that the LCM of 148,765,431,668,990 is 89641595340.
