The LCM of 661,836,982,910,494 is 123452709380.
Find LCM of 661,836,982,910,494 with Prime Factorization
2 | 661, 836, 982, 910, 494 |
13 | 661, 418, 491, 455, 247 |
19 | 661, 418, 491, 35, 19 |
661, 22, 491, 35, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 19 x 661 x 22 x 491 x 35 x 1 = 123452709380
Therefore, the lowest common multiple of 661,836,982,910,494 is 123452709380.
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 836 x 982 x 910 x 494 = 243942553734880
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
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
982 : 1, 2, 491, 982
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
494 : 1, 2, 13, 19, 26, 38, 247, 494
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,836,982,910,494, is 1.
Now, the common factors can be found like this.
661:661
836:2x 2x 11x 19
982:2x 491
910:2x 5x 7x 13
494:2x 13x 19
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 13x 19 = 1976
Therefore, the value for common factors is 1976.
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 = 243942553734880/(1x1976)
LCM = 243942553734880/1976
LCM = 123452709380
Thus, we can understand that the LCM of 661,836,982,910,494 is 123452709380.
