Given numbers are 402,172,109,716

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

The LCM of 402,172,109,716 is 674534292.

Find LCM of 402,172,109,716 with Prime Factorization

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

2 x 2 x 201 x 43 x 109 x 179 = 674534292

Therefore, the lowest common multiple of 402,172,109,716 is 674534292.

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 172 x 109 x 716 = 5396274336

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

172 : 1, 2, 4, 43, 86, 172

109 : 1, 109

716 : 1, 2, 4, 179, 358, 716

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 402,172,109,716, is 1.

Now, the common factors can be found like this.

402:2x 3x 67

172:2x 2x 43

109:109

716:2x 2x 179

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 2 = 8

Therefore, the value for common factors is 8.

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 = 5396274336/(1x8)

LCM = 5396274336/8

LCM = 674534292

Thus, we can understand that the LCM of 402,172,109,716 is 674534292.
