Given numbers are 221,478,274

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

The LCM of 221,478,274 is 14472406.

Find LCM of 221,478,274 with Prime Factorization

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

2 x 221 x 239 x 137 = 14472406

Therefore, the lowest common multiple of 221,478,274 is 14472406.

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.

221 x 478 x 274 = 28944812

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.

221 : 1, 13, 17, 221

478 : 1, 2, 239, 478

274 : 1, 2, 137, 274

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,478,274, is 1.

Now, the common factors can be found like this.

221:13x 17

478:2x 239

274:2x 137

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

2 = 2

Therefore, the value for common factors is 2.

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 = 28944812/(1x2)

LCM = 28944812/2

LCM = 14472406

Thus, we can understand that the LCM of 221,478,274 is 14472406.

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

• LCM of 987, 284, 157
