Given numbers are 838,168,407,986

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

The LCM of 838,168,407,986 is 14124225192.

Find LCM of 838,168,407,986 with Prime Factorization

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

2 x 419 x 84 x 407 x 493 = 14124225192

Therefore, the lowest common multiple of 838,168,407,986 is 14124225192.

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.

838 x 168 x 407 x 986 = 56496900768

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.

838 : 1, 2, 419, 838

168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168

407 : 1, 11, 37, 407

986 : 1, 2, 17, 29, 34, 58, 493, 986

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 838,168,407,986, is 1.

Now, the common factors can be found like this.

838:2x 419

168:2x 2x 2x 3x 7

407:11x 37

986:2x 17x 29

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 56496900768/(1x4)

LCM = 56496900768/4

LCM = 14124225192

Thus, we can understand that the LCM of 838,168,407,986 is 14124225192.
