Calculate the LCM of 784,722,622,409

Given numbers are 784,722,622,409

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

The LCM of 784,722,622,409 is 36000369776.

Find LCM of 784,722,622,409 with Prime Factorization


2 784, 722, 622, 409
392, 361, 311, 409

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

2 x 392 x 361 x 311 x 409 = 36000369776

Therefore, the lowest common multiple of 784,722,622,409 is 36000369776.

LCM Formula to Find Lowest Common Multiple of 784,722,622,409

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.

784 x 722 x 622 x 409 = 144001479104

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.

784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784

722 : 1, 2, 19, 38, 361, 722

622 : 1, 2, 311, 622

409 : 1, 409

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,722,622,409, is 1.

Now, the common factors can be found like this.

784:2x 2x 2x 2x 7x 7

722:2x 19x 19

622:2x 311

409:409

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 144001479104/(1x4)

LCM = 144001479104/4

LCM = 36000369776

Thus, we can understand that the LCM of 784,722,622,409 is 36000369776.
