Given numbers are 321,749,947

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

The LCM of 321,749,947 is 2127909.

Find LCM of 321,749,947 with Prime Factorization

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

107 x 3 x 7 x 947 = 2127909

Therefore, the lowest common multiple of 321,749,947 is 2127909.

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.

321 x 749 x 947 = 227686263

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.

321 : 1, 3, 107, 321

749 : 1, 7, 107, 749

947 : 1, 947

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 321,749,947, is 1.

Now, the common factors can be found like this.

321:3x 107

749:7x 107

947:947

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 = 227686263/(1x107)

LCM = 227686263/107

LCM = 2127909

Thus, we can understand that the LCM of 321,749,947 is 2127909.

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

• LCM of 795, 827, 452
• LCM of 302, 530, 482
