Find LCM of 298,255,770,638,153 with Prime Factorization
| 2 | 298, 255, 770, 638, 153 |
| 3 | 149, 255, 385, 319, 153 |
| 5 | 149, 85, 385, 319, 51 |
| 11 | 149, 17, 77, 319, 51 |
| 17 | 149, 17, 7, 29, 51 |
| 149, 1, 7, 29, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 17 x 149 x 1 x 7 x 29 x 3 = 509057010
Therefore, the lowest common multiple of 298,255,770,638,153 is 509057010.
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.
298 x 255 x 770 x 638 x 153 = 5711619652200
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.
298 : 1, 2, 149, 298
255 : 1, 3, 5, 15, 17, 51, 85, 255
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
638 : 1, 2, 11, 22, 29, 58, 319, 638
153 : 1, 3, 9, 17, 51, 153
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 298,255,770,638,153, is 1.
Now, the common factors can be found like this.
298:2x 149
255:3x 5x 17
770:2x 5x 7x 11
638:2x 11x 29
153:3x 3x 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 11x 17 = 11220
Therefore, the value for common factors is 11220.
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 = 5711619652200/(1x11220)
LCM = 5711619652200/11220
LCM = 509057010
Thus, we can understand that the LCM of 298,255,770,638,153 is 509057010.
