Given numbers are 124,983,668,421

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

The LCM of 124,983,668,421 is 8569860844.

Find LCM of 124,983,668,421 with Prime Factorization

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

2 x 2 x 31 x 983 x 167 x 421 = 8569860844

Therefore, the lowest common multiple of 124,983,668,421 is 8569860844.

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.

124 x 983 x 668 x 421 = 34279443376

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.

124 : 1, 2, 4, 31, 62, 124

983 : 1, 983

668 : 1, 2, 4, 167, 334, 668

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 124,983,668,421, is 1.

Now, the common factors can be found like this.

124:2x 2x 31

983:983

668:2x 2x 167

421:421

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 = 34279443376/(1x4)

LCM = 34279443376/4

LCM = 8569860844

Thus, we can understand that the LCM of 124,983,668,421 is 8569860844.
