Given numbers are 194,326,402,638

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

The LCM of 194,326,402,638 is 2027571018.

Find LCM of 194,326,402,638 with Prime Factorization

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

2 x 97 x 163 x 201 x 319 = 2027571018

Therefore, the lowest common multiple of 194,326,402,638 is 2027571018.

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.

194 x 326 x 402 x 638 = 16220568144

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.

194 : 1, 2, 97, 194

326 : 1, 2, 163, 326

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

638 : 1, 2, 11, 22, 29, 58, 319, 638

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 194,326,402,638, is 2.

Now, the common factors can be found like this.

194:2x 97

326:2x 163

402:2x 3x 67

638:2x 11x 29

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 16220568144/(2x4)

LCM = 16220568144/8

LCM = 2027571018

Thus, we can understand that the LCM of 194,326,402,638 is 2027571018.
