Given numbers are 697,867,280,298,256
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 697,867,280,298,256 is 47456666880.
Find LCM of 697,867,280,298,256 with Prime Factorization
| 2 | 697, 867, 280, 298, 256 |
| 2 | 697, 867, 140, 149, 128 |
| 2 | 697, 867, 70, 149, 64 |
| 17 | 697, 867, 35, 149, 32 |
| 41, 51, 35, 149, 32 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 17 x 41 x 51 x 35 x 149 x 32 = 47456666880
Therefore, the lowest common multiple of 697,867,280,298,256 is 47456666880.
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.
697 x 867 x 280 x 298 x 256 = 12908213391360
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.
697 : 1, 17, 41, 697
867 : 1, 3, 17, 51, 289, 867
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
298 : 1, 2, 149, 298
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 697,867,280,298,256, is 1.
Now, the common factors can be found like this.
697:17x 41
867:3x 17x 17
280:2x 2x 2x 5x 7
298:2x 149
256:2x 2x 2x 2x 2x 2x 2x 2
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 2x 17 = 272
Therefore, the value for common factors is 272.
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 = 12908213391360/(1x272)
LCM = 12908213391360/272
LCM = 47456666880
Thus, we can understand that the LCM of 697,867,280,298,256 is 47456666880.
