Given numbers are 646,171,709,463

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

The LCM of 646,171,709,463 is 1908544338.

Find LCM of 646,171,709,463 with Prime Factorization

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

19 x 34 x 9 x 709 x 463 = 1908544338

Therefore, the lowest common multiple of 646,171,709,463 is 1908544338.

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.

646 x 171 x 709 x 463 = 36262342422

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.

646 : 1, 2, 17, 19, 34, 38, 323, 646

171 : 1, 3, 9, 19, 57, 171

709 : 1, 709

463 : 1, 463

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,171,709,463, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

171:3x 3x 19

709:709

463:463

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

19 = 19

Therefore, the value for common factors is 19.

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 = 36262342422/(1x19)

LCM = 36262342422/19

LCM = 1908544338

Thus, we can understand that the LCM of 646,171,709,463 is 1908544338.
