Given numbers are 391,784,211,702,782

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

The LCM of 391,784,211,702,782 is 22702955184.

Find LCM of 391,784,211,702,782 with Prime Factorization

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

2 x 17 x 23 x 1 x 392 x 211 x 351 x 1 = 22702955184

Therefore, the lowest common multiple of 391,784,211,702,782 is 22702955184.

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.

391 x 784 x 211 x 702 x 782 = 35507421907776

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.

391 : 1, 17, 23, 391

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

211 : 1, 211

702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702

782 : 1, 2, 17, 23, 34, 46, 391, 782

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,784,211,702,782, is 1.

Now, the common factors can be found like this.

391:17x 23

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

211:211

702:2x 3x 3x 3x 13

782:2x 17x 23

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 17x 23 = 1564

Therefore, the value for common factors is 1564.

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 = 35507421907776/(1x1564)

LCM = 35507421907776/1564

LCM = 22702955184

Thus, we can understand that the LCM of 391,784,211,702,782 is 22702955184.
