Given numbers are 642,517,107

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

The LCM of 642,517,107 is 331914.

Find LCM of 642,517,107 with Prime Factorization

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

107 x 6 x 517 x 1 = 331914

Therefore, the lowest common multiple of 642,517,107 is 331914.

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.

642 x 517 x 107 = 35514798

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.

642 : 1, 2, 3, 6, 107, 214, 321, 642

517 : 1, 11, 47, 517

107 : 1, 107

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,517,107, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

517:11x 47

107:107

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

107 = 107

Therefore, the value for common factors is 107.

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 = 35514798/(1x107)

LCM = 35514798/107

LCM = 331914

Thus, we can understand that the LCM of 642,517,107 is 331914.

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

• LCM of 923, 999, 689
• LCM of 495, 611, 903
