Calculate the LCM of 917,759,759,820

Given numbers are 917,759,759,820

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

The LCM of 917,759,759,820 is 570722460.

Find LCM of 917,759,759,820 with Prime Factorization


3 917, 759, 759, 820
11 917, 253, 253, 820
23 917, 23, 23, 820
917, 1, 1, 820

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

3 x 11 x 23 x 917 x 1 x 1 x 820 = 570722460

Therefore, the lowest common multiple of 917,759,759,820 is 570722460.

LCM Formula to Find Lowest Common Multiple of 917,759,759,820

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.

917 x 759 x 759 x 820 = 433178347140

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.

917 : 1, 7, 131, 917

759 : 1, 3, 11, 23, 33, 69, 253, 759

759 : 1, 3, 11, 23, 33, 69, 253, 759

820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 917,759,759,820, is 1.

Now, the common factors can be found like this.

917:7x 131

759:3x 11x 23

759:3x 11x 23

820:2x 2x 5x 41

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

3x 11x 23 = 759

Therefore, the value for common factors is 759.

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 = 433178347140/(1x759)

LCM = 433178347140/759

LCM = 570722460

Thus, we can understand that the LCM of 917,759,759,820 is 570722460.
