Given numbers are 247,117,784

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

The LCM of 247,117,784 is 1742832.

Find LCM of 247,117,784 with Prime Factorization

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

13 x 19 x 9 x 784 = 1742832

Therefore, the lowest common multiple of 247,117,784 is 1742832.

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.

247 x 117 x 784 = 22656816

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.

247 : 1, 13, 19, 247

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

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 247,117,784, is 1.

Now, the common factors can be found like this.

247:13x 19

117:3x 3x 13

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.

13 = 13

Therefore, the value for common factors is 13.

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 = 22656816/(1x13)

LCM = 22656816/13

LCM = 1742832

Thus, we can understand that the LCM of 247,117,784 is 1742832.
