Given numbers are 646,527,289

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

The LCM of 646,527,289 is 340442.

Find LCM of 646,527,289 with Prime Factorization

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

17 x 38 x 31 x 17 = 340442

Therefore, the lowest common multiple of 646,527,289 is 340442.

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 527 x 289 = 98387738

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

527 : 1, 17, 31, 527

289 : 1, 17, 289

17 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,527,289, is 17.

Now, the common factors can be found like this.

646:2x 17x 19

527:17x 31

289:17x 17

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

17 = 17

Therefore, the value for common factors is 17.

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 = 98387738/(17x17)

LCM = 98387738/289

LCM = 340442

Thus, we can understand that the LCM of 646,527,289 is 340442.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 967, 762, 530
