Given numbers are 291,783,678,478

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

The LCM of 291,783,678,478 is 4102417314.

Find LCM of 291,783,678,478 with Prime Factorization

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

2 x 3 x 97 x 261 x 113 x 239 = 4102417314

Therefore, the lowest common multiple of 291,783,678,478 is 4102417314.

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.

291 x 783 x 678 x 478 = 73843511652

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.

291 : 1, 3, 97, 291

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

678 : 1, 2, 3, 6, 113, 226, 339, 678

478 : 1, 2, 239, 478

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,783,678,478, is 1.

Now, the common factors can be found like this.

291:3x 97

783:3x 3x 3x 29

678:2x 3x 113

478:2x 239

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 73843511652/(1x18)

LCM = 73843511652/18

LCM = 4102417314

Thus, we can understand that the LCM of 291,783,678,478 is 4102417314.
