Given numbers are 221,54,790

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

The LCM of 221,54,790 is 4713930.

Find LCM of 221,54,790 with Prime Factorization

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

2 x 221 x 27 x 395 = 4713930

Therefore, the lowest common multiple of 221,54,790 is 4713930.

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 54 x 790 = 9427860

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

54 : 1, 2, 3, 6, 9, 18, 27, 54

790 : 1, 2, 5, 10, 79, 158, 395, 790

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,54,790, is 1.

Now, the common factors can be found like this.

221:13x 17

54:2x 3x 3x 3

790:2x 5x 79

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 = 9427860/(1x2)

LCM = 9427860/2

LCM = 4713930

Thus, we can understand that the LCM of 221,54,790 is 4713930.

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

• LCM of 801, 48, 708
• LCM of 515, 57, 987
