Calculate the LCM of 721,309,578,159

Given numbers are 721,309,578,159

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

The LCM of 721,309,578,159 is 66261342.

Find LCM of 721,309,578,159 with Prime Factorization


3 721, 309, 578, 159
103 721, 103, 578, 53
7, 1, 578, 53

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

3 x 103 x 7 x 1 x 578 x 53 = 66261342

Therefore, the lowest common multiple of 721,309,578,159 is 66261342.

LCM Formula to Find Lowest Common Multiple of 721,309,578,159

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 309 x 578 x 159 = 20474754678

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

309 : 1, 3, 103, 309

578 : 1, 2, 17, 34, 289, 578

159 : 1, 3, 53, 159

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,309,578,159, is 1.

Now, the common factors can be found like this.

721:7x 103

309:3x 103

578:2x 17x 17

159:3x 53

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

3x 103 = 309

Therefore, the value for common factors is 309.

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 = 20474754678/(1x309)

LCM = 20474754678/309

LCM = 66261342

Thus, we can understand that the LCM of 721,309,578,159 is 66261342.
