Calculate the LCM of 225,805,438,931

Given numbers are 225,805,438,931

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

The LCM of 225,805,438,931 is 703417050.

Find LCM of 225,805,438,931 with Prime Factorization


3 225, 805, 438, 931
5 75, 805, 146, 931
7 15, 161, 146, 931
15, 23, 146, 133

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

3 x 5 x 7 x 15 x 23 x 146 x 133 = 703417050

Therefore, the lowest common multiple of 225,805,438,931 is 703417050.

LCM Formula to Find Lowest Common Multiple of 225,805,438,931

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.

225 x 805 x 438 x 931 = 73858790250

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.

225 : 1, 3, 5, 9, 15, 25, 45, 75, 225

805 : 1, 5, 7, 23, 35, 115, 161, 805

438 : 1, 2, 3, 6, 73, 146, 219, 438

931 : 1, 7, 19, 49, 133, 931

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 225,805,438,931, is 1.

Now, the common factors can be found like this.

225:3x 3x 5x 5

805:5x 7x 23

438:2x 3x 73

931:7x 7x 19

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

3x 5x 7 = 105

Therefore, the value for common factors is 105.

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 = 73858790250/(1x105)

LCM = 73858790250/105

LCM = 703417050

Thus, we can understand that the LCM of 225,805,438,931 is 703417050.
