Given numbers are 185,194,840,784

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

The LCM of 185,194,840,784 is 42206640.

Find LCM of 185,194,840,784 with Prime Factorization

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

2 x 2 x 2 x 5 x 7 x 37 x 97 x 3 x 14 = 42206640

Therefore, the lowest common multiple of 185,194,840,784 is 42206640.

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.

185 x 194 x 840 x 784 = 23635718400

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.

185 : 1, 5, 37, 185

194 : 1, 2, 97, 194

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 185,194,840,784, is 1.

Now, the common factors can be found like this.

185:5x 37

194:2x 97

840:2x 2x 2x 3x 5x 7

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

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

2x 2x 2x 2x 5x 7 = 560

Therefore, the value for common factors is 560.

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 = 23635718400/(1x560)

LCM = 23635718400/560

LCM = 42206640

Thus, we can understand that the LCM of 185,194,840,784 is 42206640.
