Given numbers are 451,64,861

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

The LCM of 451,64,861 is 606144.

Find LCM of 451,64,861 with Prime Factorization

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

41 x 11 x 64 x 21 = 606144

Therefore, the lowest common multiple of 451,64,861 is 606144.

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.

451 x 64 x 861 = 24851904

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.

451 : 1, 11, 41, 451

64 : 1, 2, 4, 8, 16, 32, 64

861 : 1, 3, 7, 21, 41, 123, 287, 861

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 451,64,861, is 1.

Now, the common factors can be found like this.

451:11x 41

64:2x 2x 2x 2x 2x 2

861:3x 7x 41

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

41 = 41

Therefore, the value for common factors is 41.

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 = 24851904/(1x41)

LCM = 24851904/41

LCM = 606144

Thus, we can understand that the LCM of 451,64,861 is 606144.

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

• LCM of 744, 50, 904
• LCM of 214, 98, 658
