Calculate the LCM of 701,805,690,802

Given numbers are 701,805,690,802

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

The LCM of 701,805,690,802 is 1357717830.

Find LCM of 701,805,690,802 with Prime Factorization


2 701, 805, 690, 802
5 701, 805, 345, 401
23 701, 161, 69, 401
701, 7, 3, 401

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

2 x 5 x 23 x 701 x 7 x 3 x 401 = 1357717830

Therefore, the lowest common multiple of 701,805,690,802 is 1357717830.

LCM Formula to Find Lowest Common Multiple of 701,805,690,802

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.

701 x 805 x 690 x 802 = 312275100900

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.

701 : 1, 701

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

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

802 : 1, 2, 401, 802

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 701,805,690,802, is 1.

Now, the common factors can be found like this.

701:701

805:5x 7x 23

690:2x 3x 5x 23

802:2x 401

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

2x 5x 23 = 230

Therefore, the value for common factors is 230.

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 = 312275100900/(1x230)

LCM = 312275100900/230

LCM = 1357717830

Thus, we can understand that the LCM of 701,805,690,802 is 1357717830.
