Given numbers are 401,425,221

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

The LCM of 401,425,221 is 2215525.

Find LCM of 401,425,221 with Prime Factorization

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

17 x 401 x 25 x 13 = 2215525

Therefore, the lowest common multiple of 401,425,221 is 2215525.

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.

401 x 425 x 221 = 37663925

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.

401 : 1, 401

425 : 1, 5, 17, 25, 85, 425

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 401,425,221, is 1.

Now, the common factors can be found like this.

401:401

425:5x 5x 17

221:13x 17

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

17 = 17

Therefore, the value for common factors is 17.

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 = 37663925/(1x17)

LCM = 37663925/17

LCM = 2215525

Thus, we can understand that the LCM of 401,425,221 is 2215525.

Here are some samples of LCM of two or more Numbers calculations.
