Given numbers are 983,781,686,901,656
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 983,781,686,901,656 is 155642178922384.
Find LCM of 983,781,686,901,656 with Prime Factorization
2 | 983, 781, 686, 901, 656 |
983, 781, 343, 901, 328 |
Multiply the prime numbers at the bottom and the left side.
2 x 983 x 781 x 343 x 901 x 328 = 155642178922384
Therefore, the lowest common multiple of 983,781,686,901,656 is 155642178922384.
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.
983 x 781 x 686 x 901 x 656 = 311284357844768
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.
983 : 1, 983
781 : 1, 11, 71, 781
686 : 1, 2, 7, 14, 49, 98, 343, 686
901 : 1, 17, 53, 901
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 983,781,686,901,656, is 1.
Now, the common factors can be found like this.
983:983
781:11x 71
686:2x 7x 7x 7
901:17x 53
656:2x 2x 2x 2x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 311284357844768/(1x2)
LCM = 311284357844768/2
LCM = 155642178922384
Thus, we can understand that the LCM of 983,781,686,901,656 is 155642178922384.
