The LCM of 867,930,969,686 is 1751574090.

Find LCM of 867,930,969,686 with Prime Factorization


2 867, 930, 969, 686
3 867, 465, 969, 343
17 289, 155, 323, 343
17, 155, 19, 343

Multiply the prime numbers at the bottom and the left side.

2 x 3 x 17 x 17 x 155 x 19 x 343 = 1751574090

Therefore, the lowest common multiple of 867,930,969,686 is 1751574090.

LCM Formula to Find Lowest Common Multiple of 867,930,969,686

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.

867 x 930 x 969 x 686 = 535981671540

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.

867 : 1, 3, 17, 51, 289, 867

930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930

969 : 1, 3, 17, 19, 51, 57, 323, 969

686 : 1, 2, 7, 14, 49, 98, 343, 686

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 867,930,969,686, is 1.

Now, the common factors can be found like this.

867:3x 17x 17

930:2x 3x 5x 31

969:3x 17x 19

686:2x 7x 7x 7

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 17 = 306

Therefore, the value for common factors is 306.

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 = 535981671540/(1x306)

LCM = 535981671540/306

LCM = 1751574090

Thus, we can understand that the LCM of 867,930,969,686 is 1751574090.
