Calculate the LCM of 557,974,858,405

Given numbers are 557,974,858,405

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

The LCM of 557,974,858,405 is 31419929970.

Find LCM of 557,974,858,405 with Prime Factorization


2 557, 974, 858, 405
3 557, 487, 429, 405
557, 487, 143, 135

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

2 x 3 x 557 x 487 x 143 x 135 = 31419929970

Therefore, the lowest common multiple of 557,974,858,405 is 31419929970.

LCM Formula to Find Lowest Common Multiple of 557,974,858,405

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.

557 x 974 x 858 x 405 = 188519579820

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.

557 : 1, 557

974 : 1, 2, 487, 974

858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858

405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 557,974,858,405, is 1.

Now, the common factors can be found like this.

557:557

974:2x 487

858:2x 3x 11x 13

405:3x 3x 3x 3x 5

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 188519579820/(1x6)

LCM = 188519579820/6

LCM = 31419929970

Thus, we can understand that the LCM of 557,974,858,405 is 31419929970.
