Calculate the LCM of 721,133,646,876

Given numbers are 721,133,646,876

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

The LCM of 721,133,646,876 is 204005508.

Find LCM of 721,133,646,876 with Prime Factorization


2 721, 133, 646, 876
7 721, 133, 323, 438
19 103, 19, 323, 438
103, 1, 17, 438

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

2 x 7 x 19 x 103 x 1 x 17 x 438 = 204005508

Therefore, the lowest common multiple of 721,133,646,876 is 204005508.

LCM Formula to Find Lowest Common Multiple of 721,133,646,876

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.

721 x 133 x 646 x 876 = 54265465128

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.

721 : 1, 7, 103, 721

133 : 1, 7, 19, 133

646 : 1, 2, 17, 19, 34, 38, 323, 646

876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,133,646,876, is 1.

Now, the common factors can be found like this.

721:7x 103

133:7x 19

646:2x 17x 19

876:2x 2x 3x 73

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

2x 7x 19 = 266

Therefore, the value for common factors is 266.

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 = 54265465128/(1x266)

LCM = 54265465128/266

LCM = 204005508

Thus, we can understand that the LCM of 721,133,646,876 is 204005508.
