Find LCM of 295,280,981,767,840 with Prime Factorization
| 2 | 295, 280, 981, 767, 840 |
| 2 | 295, 140, 981, 767, 420 |
| 2 | 295, 70, 981, 767, 210 |
| 3 | 295, 35, 981, 767, 105 |
| 5 | 295, 35, 327, 767, 35 |
| 7 | 59, 7, 327, 767, 7 |
| 59 | 59, 1, 327, 767, 1 |
| 1, 1, 327, 13, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 7 x 59 x 1 x 1 x 327 x 13 x 1 = 210679560
Therefore, the lowest common multiple of 295,280,981,767,840 is 210679560.
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.
295 x 280 x 981 x 767 x 840 = 52206394968000
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.
295 : 1, 5, 59, 295
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
981 : 1, 3, 9, 109, 327, 981
767 : 1, 13, 59, 767
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 295,280,981,767,840, is 1.
Now, the common factors can be found like this.
295:5x 59
280:2x 2x 2x 5x 7
981:3x 3x 109
767:13x 59
840:2x 2x 2x 3x 5x 7
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 5x 5x 7x 59 = 247800
Therefore, the value for common factors is 247800.
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 = 52206394968000/(1x247800)
LCM = 52206394968000/247800
LCM = 210679560
Thus, we can understand that the LCM of 295,280,981,767,840 is 210679560.
