Given numbers are 421,411,411,154

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

The LCM of 421,411,411,154 is 26646774.

Find LCM of 421,411,411,154 with Prime Factorization

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

3 x 137 x 421 x 1 x 1 x 154 = 26646774

Therefore, the lowest common multiple of 421,411,411,154 is 26646774.

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 411 x 411 x 154 = 10951824114

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

411 : 1, 3, 137, 411

411 : 1, 3, 137, 411

154 : 1, 2, 7, 11, 14, 22, 77, 154

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,411,411,154, is 1.

Now, the common factors can be found like this.

421:421

411:3x 137

411:3x 137

154:2x 7x 11

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

3x 137 = 411

Therefore, the value for common factors is 411.

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 = 10951824114/(1x411)

LCM = 10951824114/411

LCM = 26646774

Thus, we can understand that the LCM of 421,411,411,154 is 26646774.
