Find LCM of 966,741,988,861 with Prime Factorization
| 2 | 966, 741, 988, 861 |
| 3 | 483, 741, 494, 861 |
| 7 | 161, 247, 494, 287 |
| 13 | 23, 247, 494, 41 |
| 19 | 23, 19, 38, 41 |
| 23, 1, 2, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 13 x 19 x 23 x 1 x 2 x 41 = 19565364
Therefore, the lowest common multiple of 966,741,988,861 is 19565364.
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.
966 x 741 x 988 x 861 = 608913258408
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.
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
741 : 1, 3, 13, 19, 39, 57, 247, 741
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 966,741,988,861, is 1.
Now, the common factors can be found like this.
966:2x 3x 7x 23
741:3x 13x 19
988:2x 2x 13x 19
861:3x 7x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 7x 13x 19 = 31122
Therefore, the value for common factors is 31122.
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 = 608913258408/(1x31122)
LCM = 608913258408/31122
LCM = 19565364
Thus, we can understand that the LCM of 966,741,988,861 is 19565364.
