Calculate the LCM of 625,509,642,404

Given numbers are 625,509,642,404

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

The LCM of 625,509,642,404 is 41255722500.

Find LCM of 625,509,642,404 with Prime Factorization


2 625, 509, 642, 404
625, 509, 321, 202

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

2 x 625 x 509 x 321 x 202 = 41255722500

Therefore, the lowest common multiple of 625,509,642,404 is 41255722500.

LCM Formula to Find Lowest Common Multiple of 625,509,642,404

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.

625 x 509 x 642 x 404 = 82511445000

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.

625 : 1, 5, 25, 125, 625

509 : 1, 509

642 : 1, 2, 3, 6, 107, 214, 321, 642

404 : 1, 2, 4, 101, 202, 404

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 625,509,642,404, is 1.

Now, the common factors can be found like this.

625:5x 5x 5x 5

509:509

642:2x 3x 107

404:2x 2x 101

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

2 = 2

Therefore, the value for common factors is 2.

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 = 82511445000/(1x2)

LCM = 82511445000/2

LCM = 41255722500

Thus, we can understand that the LCM of 625,509,642,404 is 41255722500.
