Given numbers are 676,102,842,421

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

The LCM of 676,102,842,421 is 14514396.

Find LCM of 676,102,842,421 with Prime Factorization

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

2 x 421 x 338 x 51 x 1 x 1 = 14514396

Therefore, the lowest common multiple of 676,102,842,421 is 14514396.

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.

676 x 102 x 842 x 421 = 24442242864

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.

676 : 1, 2, 4, 13, 26, 52, 169, 338, 676

102 : 1, 2, 3, 6, 17, 34, 51, 102

842 : 1, 2, 421, 842

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 676,102,842,421, is 1.

Now, the common factors can be found like this.

676:2x 2x 13x 13

102:2x 3x 17

842:2x 421

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 2x 421 = 1684

Therefore, the value for common factors is 1684.

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 = 24442242864/(1x1684)

LCM = 24442242864/1684

LCM = 14514396

Thus, we can understand that the LCM of 676,102,842,421 is 14514396.
