Given numbers are 686,238,924,838,854

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 686,238,924,838,854 is 19672557828.

Find LCM of 686,238,924,838,854 with Prime Factorization

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

2 x 7 x 49 x 17 x 66 x 419 x 61 = 19672557828

Therefore, the lowest common multiple of 686,238,924,838,854 is 19672557828.

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.

686 x 238 x 924 x 838 x 854 = 107962997360064

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.

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

238 : 1, 2, 7, 14, 17, 34, 119, 238

924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924

838 : 1, 2, 419, 838

854 : 1, 2, 7, 14, 61, 122, 427, 854

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,238,924,838,854, is 2.

Now, the common factors can be found like this.

686:2x 7x 7x 7

238:2x 7x 17

924:2x 2x 3x 7x 11

838:2x 419

854:2x 7x 61

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 7x 7x 7 = 2744

Therefore, the value for common factors is 2744.

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 = 107962997360064/(2x2744)

LCM = 107962997360064/5488

LCM = 19672557828

Thus, we can understand that the LCM of 686,238,924,838,854 is 19672557828.
