Given numbers are 669,321,985

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

The LCM of 669,321,985 is 70509255.

Find LCM of 669,321,985 with Prime Factorization

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

3 x 223 x 107 x 985 = 70509255

Therefore, the lowest common multiple of 669,321,985 is 70509255.

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.

669 x 321 x 985 = 211527765

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.

669 : 1, 3, 223, 669

321 : 1, 3, 107, 321

985 : 1, 5, 197, 985

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,321,985, is 1.

Now, the common factors can be found like this.

669:3x 223

321:3x 107

985:5x 197

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

3 = 3

Therefore, the value for common factors is 3.

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 = 211527765/(1x3)

LCM = 211527765/3

LCM = 70509255

Thus, we can understand that the LCM of 669,321,985 is 70509255.

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

• LCM of 966, 240, 768
• LCM of 968, 144, 118
