Given numbers are 239,121,220

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

The LCM of 239,121,220 is 578380.

Find LCM of 239,121,220 with Prime Factorization

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

11 x 239 x 11 x 20 = 578380

Therefore, the lowest common multiple of 239,121,220 is 578380.

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.

239 x 121 x 220 = 6362180

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.

239 : 1, 239

121 : 1, 11, 121

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 239,121,220, is 1.

Now, the common factors can be found like this.

239:239

121:11x 11

220:2x 2x 5x 11

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

11 = 11

Therefore, the value for common factors is 11.

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 = 6362180/(1x11)

LCM = 6362180/11

LCM = 578380

Thus, we can understand that the LCM of 239,121,220 is 578380.

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

• LCM of 744, 688, 806
• LCM of 305, 350, 412
