Find LCM of 298,149,902,855,720 with Prime Factorization
| 2 | 298, 149, 902, 855, 720 |
| 3 | 149, 149, 451, 855, 360 |
| 3 | 149, 149, 451, 285, 120 |
| 5 | 149, 149, 451, 95, 40 |
| 149 | 149, 149, 451, 19, 8 |
| 1, 1, 451, 19, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 149 x 1 x 1 x 451 x 19 x 8 = 919282320
Therefore, the lowest common multiple of 298,149,902,855,720 is 919282320.
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 149 x 902 x 855 x 720 = 24655151822400
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
149 : 1, 149
902 : 1, 2, 11, 22, 41, 82, 451, 902
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 298,149,902,855,720, is 1.
Now, the common factors can be found like this.
298:2x 149
149:149
902:2x 11x 41
855:3x 3x 5x 19
720:2x 2x 2x 2x 3x 3x 5
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 3x 5x 149 = 26820
Therefore, the value for common factors is 26820.
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 = 24655151822400/(1x26820)
LCM = 24655151822400/26820
LCM = 919282320
Thus, we can understand that the LCM of 298,149,902,855,720 is 919282320.
