Given numbers are 478,201,338,661

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

The LCM of 478,201,338,661 is 10732777302.

Find LCM of 478,201,338,661 with Prime Factorization

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

2 x 239 x 201 x 169 x 661 = 10732777302

Therefore, the lowest common multiple of 478,201,338,661 is 10732777302.

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.

478 x 201 x 338 x 661 = 21465554604

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.

478 : 1, 2, 239, 478

201 : 1, 3, 67, 201

338 : 1, 2, 13, 26, 169, 338

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 478,201,338,661, is 1.

Now, the common factors can be found like this.

478:2x 239

201:3x 67

338:2x 13x 13

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.

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 = 21465554604/(1x2)

LCM = 21465554604/2

LCM = 10732777302

Thus, we can understand that the LCM of 478,201,338,661 is 10732777302.
