Given numbers are 402,170,661,226,661

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

The LCM of 402,170,661,226,661 is 2552259810.

Find LCM of 402,170,661,226,661 with Prime Factorization

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

2 x 661 x 201 x 85 x 1 x 113 x 1 = 2552259810

Therefore, the lowest common multiple of 402,170,661,226,661 is 2552259810.

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.

402 x 170 x 661 x 226 x 661 = 6748174937640

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.

402 : 1, 2, 3, 6, 67, 134, 201, 402

170 : 1, 2, 5, 10, 17, 34, 85, 170

661 : 1, 661

226 : 1, 2, 113, 226

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 402,170,661,226,661, is 1.

Now, the common factors can be found like this.

402:2x 3x 67

170:2x 5x 17

661:661

226:2x 113

661:661

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

2x 2x 661 = 2644

Therefore, the value for common factors is 2644.

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 = 6748174937640/(1x2644)

LCM = 6748174937640/2644

LCM = 2552259810

Thus, we can understand that the LCM of 402,170,661,226,661 is 2552259810.
