Given numbers are 961,107,642

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

The LCM of 961,107,642 is 616962.

Find LCM of 961,107,642 with Prime Factorization

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

107 x 961 x 1 x 6 = 616962

Therefore, the lowest common multiple of 961,107,642 is 616962.

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.

961 x 107 x 642 = 66014934

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.

961 : 1, 31, 961

107 : 1, 107

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 961,107,642, is 1.

Now, the common factors can be found like this.

961:31x 31

107:107

642:2x 3x 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 = 66014934/(1x107)

LCM = 66014934/107

LCM = 616962

Thus, we can understand that the LCM of 961,107,642 is 616962.

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

• LCM of 325, 332, 485
• LCM of 220, 342, 758
