Given numbers are 690,961,961

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

The LCM of 690,961,961 is 663090.

Find LCM of 690,961,961 with Prime Factorization

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

31 x 31 x 690 x 1 x 1 = 663090

Therefore, the lowest common multiple of 690,961,961 is 663090.

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.

690 x 961 x 961 = 637229490

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.

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

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 690,961,961, is 1.

Now, the common factors can be found like this.

690:2x 3x 5x 23

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 = 637229490/(1x961)

LCM = 637229490/961

LCM = 663090

Thus, we can understand that the LCM of 690,961,961 is 663090.

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

• LCM of 933, 783, 571
