The LCM of 966,420,661,189,787 is 45226796580.
Find LCM of 966,420,661,189,787 with Prime Factorization
| 2 | 966, 420, 661, 189, 787 |
| 3 | 483, 210, 661, 189, 787 |
| 7 | 161, 70, 661, 63, 787 |
| 23, 10, 661, 9, 787 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 23 x 10 x 661 x 9 x 787 = 45226796580
Therefore, the lowest common multiple of 966,420,661,189,787 is 45226796580.
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 420 x 661 x 189 x 787 = 39890034583560
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
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
661 : 1, 661
189 : 1, 3, 7, 9, 21, 27, 63, 189
787 : 1, 787
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 966,420,661,189,787, is 1.
Now, the common factors can be found like this.
966:2x 3x 7x 23
420:2x 2x 3x 5x 7
661:661
189:3x 3x 3x 7
787:787
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 7 = 882
Therefore, the value for common factors is 882.
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 = 39890034583560/(1x882)
LCM = 39890034583560/882
LCM = 45226796580
Thus, we can understand that the LCM of 966,420,661,189,787 is 45226796580.
