Given numbers are 402,103,478,515

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

The LCM of 402,103,478,515 is 49480170.

Find LCM of 402,103,478,515 with Prime Factorization

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

2 x 103 x 201 x 1 x 239 x 5 = 49480170

Therefore, the lowest common multiple of 402,103,478,515 is 49480170.

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 103 x 478 x 515 = 10192915020

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

103 : 1, 103

478 : 1, 2, 239, 478

515 : 1, 5, 103, 515

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 402,103,478,515, is 1.

Now, the common factors can be found like this.

402:2x 3x 67

103:103

478:2x 239

515:5x 103

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

2x 103 = 206

Therefore, the value for common factors is 206.

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 = 10192915020/(1x206)

LCM = 10192915020/206

LCM = 49480170

Thus, we can understand that the LCM of 402,103,478,515 is 49480170.
