Given numbers are 628,706,947

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

The LCM of 628,706,947 is 209934748.

Find LCM of 628,706,947 with Prime Factorization

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

2 x 314 x 353 x 947 = 209934748

Therefore, the lowest common multiple of 628,706,947 is 209934748.

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.

628 x 706 x 947 = 419869496

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.

628 : 1, 2, 4, 157, 314, 628

706 : 1, 2, 353, 706

947 : 1, 947

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,706,947, is 1.

Now, the common factors can be found like this.

628:2x 2x 157

706:2x 353

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.

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 = 419869496/(1x2)

LCM = 419869496/2

LCM = 209934748

Thus, we can understand that the LCM of 628,706,947 is 209934748.

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

• LCM of 997, 251, 228
