Given numbers are 745,947,201,21

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

The LCM of 745,947,201,21 is 992659605.

Find LCM of 745,947,201,21 with Prime Factorization

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

3 x 745 x 947 x 67 x 7 = 992659605

Therefore, the lowest common multiple of 745,947,201,21 is 992659605.

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.

745 x 947 x 201 x 21 = 2977978815

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.

745 : 1, 5, 149, 745

947 : 1, 947

201 : 1, 3, 67, 201

21 : 1, 3, 7, 21

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 745,947,201,21, is 1.

Now, the common factors can be found like this.

745:5x 149

947:947

201:3x 67

21:3x 7

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 = 2977978815/(1x3)

LCM = 2977978815/3

LCM = 992659605

Thus, we can understand that the LCM of 745,947,201,21 is 992659605.

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

• LCM of 910, 548, 349, 82
