Given numbers are 690,616,169

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

The LCM of 690,616,169 is 35915880.

Find LCM of 690,616,169 with Prime Factorization

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

2 x 345 x 308 x 169 = 35915880

Therefore, the lowest common multiple of 690,616,169 is 35915880.

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 616 x 169 = 71831760

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

616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616

169 : 1, 13, 169

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,616,169, is 1.

Now, the common factors can be found like this.

690:2x 3x 5x 23

616:2x 2x 2x 7x 11

169:13x 13

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

2 = 2

Therefore, the value for common factors is 2.

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 = 71831760/(1x2)

LCM = 71831760/2

LCM = 35915880

Thus, we can understand that the LCM of 690,616,169 is 35915880.

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

• LCM of 521, 783, 173
