Given numbers are 254,56,561

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

The LCM of 254,56,561 is 3989832.

Find LCM of 254,56,561 with Prime Factorization

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

2 x 127 x 28 x 561 = 3989832

Therefore, the lowest common multiple of 254,56,561 is 3989832.

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.

254 x 56 x 561 = 7979664

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.

254 : 1, 2, 127, 254

56 : 1, 2, 4, 7, 8, 14, 28, 56

561 : 1, 3, 11, 17, 33, 51, 187, 561

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 254,56,561, is 1.

Now, the common factors can be found like this.

254:2x 127

56:2x 2x 2x 7

561:3x 11x 17

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 = 7979664/(1x2)

LCM = 7979664/2

LCM = 3989832

Thus, we can understand that the LCM of 254,56,561 is 3989832.

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

• LCM of 218, 81, 472
• LCM of 114, 29, 565
