Calculate the LCM of 521,412,918,618,931

Given numbers are 521,412,918,618,931

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

The LCM of 521,412,918,618,931 is 91727024508.

Find LCM of 521,412,918,618,931 with Prime Factorization


2 521, 412, 918, 618, 931
3 521, 206, 459, 309, 931
103 521, 206, 153, 103, 931
521, 2, 153, 1, 931

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

2 x 3 x 103 x 521 x 2 x 153 x 1 x 931 = 91727024508

Therefore, the lowest common multiple of 521,412,918,618,931 is 91727024508.

LCM Formula to Find Lowest Common Multiple of 521,412,918,618,931

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.

521 x 412 x 918 x 618 x 931 = 113374602291888

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.

521 : 1, 521

412 : 1, 2, 4, 103, 206, 412

918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918

618 : 1, 2, 3, 6, 103, 206, 309, 618

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 521,412,918,618,931, is 1.

Now, the common factors can be found like this.

521:521

412:2x 2x 103

918:2x 3x 3x 3x 17

618:2x 3x 103

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.

2x 2x 3x 103 = 1236

Therefore, the value for common factors is 1236.

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 = 113374602291888/(1x1236)

LCM = 113374602291888/1236

LCM = 91727024508

Thus, we can understand that the LCM of 521,412,918,618,931 is 91727024508.
