Given numbers are 402,166,747,409

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

The LCM of 402,166,747,409 is 40940082.

Find LCM of 402,166,747,409 with Prime Factorization

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

2 x 3 x 83 x 67 x 1 x 3 x 409 = 40940082

Therefore, the lowest common multiple of 402,166,747,409 is 40940082.

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 166 x 747 x 409 = 20388160836

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

166 : 1, 2, 83, 166

747 : 1, 3, 9, 83, 249, 747

409 : 1, 409

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 402,166,747,409, is 1.

Now, the common factors can be found like this.

402:2x 3x 67

166:2x 83

747:3x 3x 83

409:409

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

2x 3x 83 = 498

Therefore, the value for common factors is 498.

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 = 20388160836/(1x498)

LCM = 20388160836/498

LCM = 40940082

Thus, we can understand that the LCM of 402,166,747,409 is 40940082.
