Given numbers are 741,326,221,788

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

The LCM of 741,326,221,788 is 1618009068.

Find LCM of 741,326,221,788 with Prime Factorization

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

2 x 13 x 57 x 163 x 17 x 394 = 1618009068

Therefore, the lowest common multiple of 741,326,221,788 is 1618009068.

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.

741 x 326 x 221 x 788 = 42068235768

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.

741 : 1, 3, 13, 19, 39, 57, 247, 741

326 : 1, 2, 163, 326

221 : 1, 13, 17, 221

788 : 1, 2, 4, 197, 394, 788

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 741,326,221,788, is 1.

Now, the common factors can be found like this.

741:3x 13x 19

326:2x 163

221:13x 17

788:2x 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.

2x 13 = 26

Therefore, the value for common factors is 26.

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 = 42068235768/(1x26)

LCM = 42068235768/26

LCM = 1618009068

Thus, we can understand that the LCM of 741,326,221,788 is 1618009068.
