Find LCM of 661,420,811,168,273 with Prime Factorization
2 | 661, 420, 811, 168, 273 |
2 | 661, 210, 811, 84, 273 |
3 | 661, 105, 811, 42, 273 |
7 | 661, 35, 811, 14, 91 |
661, 5, 811, 2, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 661 x 5 x 811 x 2 x 13 = 5853895320
Therefore, the lowest common multiple of 661,420,811,168,273 is 5853895320.
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.
661 x 420 x 811 x 168 x 273 = 10326271344480
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.
661 : 1, 661
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
811 : 1, 811
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
273 : 1, 3, 7, 13, 21, 39, 91, 273
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,420,811,168,273, is 1.
Now, the common factors can be found like this.
661:661
420:2x 2x 3x 5x 7
811:811
168:2x 2x 2x 3x 7
273:3x 7x 13
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 7x 7 = 1764
Therefore, the value for common factors is 1764.
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 = 10326271344480/(1x1764)
LCM = 10326271344480/1764
LCM = 5853895320
Thus, we can understand that the LCM of 661,420,811,168,273 is 5853895320.
