Given numbers are 783,203,343,394

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

The LCM of 783,203,343,394 is 105816186.

Find LCM of 783,203,343,394 with Prime Factorization

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

7 x 29 x 27 x 1 x 49 x 394 = 105816186

Therefore, the lowest common multiple of 783,203,343,394 is 105816186.

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.

783 x 203 x 343 x 394 = 21480685758

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.

783 : 1, 3, 9, 27, 29, 87, 261, 783

203 : 1, 7, 29, 203

343 : 1, 7, 49, 343

394 : 1, 2, 197, 394

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 783,203,343,394, is 1.

Now, the common factors can be found like this.

783:3x 3x 3x 29

203:7x 29

343:7x 7x 7

394:2x 197

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

7x 29 = 203

Therefore, the value for common factors is 203.

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 = 21480685758/(1x203)

LCM = 21480685758/203

LCM = 105816186

Thus, we can understand that the LCM of 783,203,343,394 is 105816186.
