Given numbers are 421,745,421,694

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

The LCM of 421,745,421,694 is 217669630.

Find LCM of 421,745,421,694 with Prime Factorization

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

421 x 1 x 745 x 1 x 694 = 217669630

Therefore, the lowest common multiple of 421,745,421,694 is 217669630.

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.

421 x 745 x 421 x 694 = 91638914230

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.

421 : 1, 421

745 : 1, 5, 149, 745

421 : 1, 421

694 : 1, 2, 347, 694

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,745,421,694, is 1.

Now, the common factors can be found like this.

421:421

745:5x 149

421:421

694:2x 347

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

421 = 421

Therefore, the value for common factors is 421.

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 = 91638914230/(1x421)

LCM = 91638914230/421

LCM = 217669630

Thus, we can understand that the LCM of 421,745,421,694 is 217669630.
