Given numbers are 219,117,784,387

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

The LCM of 219,117,784,387 is 287934192.

Find LCM of 219,117,784,387 with Prime Factorization

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

3 x 3 x 73 x 13 x 784 x 43 = 287934192

Therefore, the lowest common multiple of 219,117,784,387 is 287934192.

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.

219 x 117 x 784 x 387 = 7774223184

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.

219 : 1, 3, 73, 219

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

784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784

387 : 1, 3, 9, 43, 129, 387

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 219,117,784,387, is 1.

Now, the common factors can be found like this.

219:3x 73

117:3x 3x 13

784:2x 2x 2x 2x 7x 7

387:3x 3x 43

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

3x 3x 3 = 27

Therefore, the value for common factors is 27.

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 = 7774223184/(1x27)

LCM = 7774223184/27

LCM = 287934192

Thus, we can understand that the LCM of 219,117,784,387 is 287934192.
