Calculate the LCM of 802,921,406,754

Given numbers are 802,921,406,754

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

The LCM of 802,921,406,754 is 1949276238.

Find LCM of 802,921,406,754 with Prime Factorization


2 802, 921, 406, 754
29 401, 921, 203, 377
401, 921, 7, 13

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

2 x 29 x 401 x 921 x 7 x 13 = 1949276238

Therefore, the lowest common multiple of 802,921,406,754 is 1949276238.

LCM Formula to Find Lowest Common Multiple of 802,921,406,754

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.

802 x 921 x 406 x 754 = 226116043608

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.

802 : 1, 2, 401, 802

921 : 1, 3, 307, 921

406 : 1, 2, 7, 14, 29, 58, 203, 406

754 : 1, 2, 13, 26, 29, 58, 377, 754

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 802,921,406,754, is 1.

Now, the common factors can be found like this.

802:2x 401

921:3x 307

406:2x 7x 29

754:2x 13x 29

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 29 = 116

Therefore, the value for common factors is 116.

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 = 226116043608/(1x116)

LCM = 226116043608/116

LCM = 1949276238

Thus, we can understand that the LCM of 802,921,406,754 is 1949276238.
