Given numbers are 667,961,961

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

The LCM of 667,961,961 is 640987.

Find LCM of 667,961,961 with Prime Factorization

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

31 x 31 x 667 x 1 x 1 = 640987

Therefore, the lowest common multiple of 667,961,961 is 640987.

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.

667 x 961 x 961 = 615988507

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.

667 : 1, 23, 29, 667

961 : 1, 31, 961

961 : 1, 31, 961

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 667,961,961, is 1.

Now, the common factors can be found like this.

667:23x 29

961:31x 31

961:31x 31

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

31x 31 = 961

Therefore, the value for common factors is 961.

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 = 615988507/(1x961)

LCM = 615988507/961

LCM = 640987

Thus, we can understand that the LCM of 667,961,961 is 640987.

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

• LCM of 224, 439, 233
• LCM of 584, 303, 605
