Given numbers are 178,819,741,661

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

The LCM of 178,819,741,661 is 1830876138.

Find LCM of 178,819,741,661 with Prime Factorization

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

3 x 13 x 178 x 21 x 19 x 661 = 1830876138

Therefore, the lowest common multiple of 178,819,741,661 is 1830876138.

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.

178 x 819 x 741 x 661 = 71404169382

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.

178 : 1, 2, 89, 178

819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819

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

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 178,819,741,661, is 1.

Now, the common factors can be found like this.

178:2x 89

819:3x 3x 7x 13

741:3x 13x 19

661:661

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

3x 13 = 39

Therefore, the value for common factors is 39.

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 = 71404169382/(1x39)

LCM = 71404169382/39

LCM = 1830876138

Thus, we can understand that the LCM of 178,819,741,661 is 1830876138.
