Given numbers are 351,978,177,861

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

The LCM of 351,978,177,861 is 1937575458.

Find LCM of 351,978,177,861 with Prime Factorization

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

3 x 117 x 326 x 59 x 287 = 1937575458

Therefore, the lowest common multiple of 351,978,177,861 is 1937575458.

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.

351 x 978 x 177 x 861 = 52314537366

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.

351 : 1, 3, 9, 13, 27, 39, 117, 351

978 : 1, 2, 3, 6, 163, 326, 489, 978

177 : 1, 3, 59, 177

861 : 1, 3, 7, 21, 41, 123, 287, 861

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 351,978,177,861, is 3.

Now, the common factors can be found like this.

351:3x 3x 3x 13

978:2x 3x 163

177:3x 59

861:3x 7x 41

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 52314537366/(3x9)

LCM = 52314537366/27

LCM = 1937575458

Thus, we can understand that the LCM of 351,978,177,861 is 1937575458.
