Given numbers are 397,505,253,742,810

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

The LCM of 397,505,253,742,810 is 3048536015910.

Find LCM of 397,505,253,742,810 with Prime Factorization

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

2 x 5 x 397 x 101 x 253 x 371 x 81 = 3048536015910

Therefore, the lowest common multiple of 397,505,253,742,810 is 3048536015910.

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.

397 x 505 x 253 x 742 x 810 = 30485360159100

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.

397 : 1, 397

505 : 1, 5, 101, 505

253 : 1, 11, 23, 253

742 : 1, 2, 7, 14, 53, 106, 371, 742

810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,505,253,742,810, is 1.

Now, the common factors can be found like this.

397:397

505:5x 101

253:11x 23

742:2x 7x 53

810:2x 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 5 = 10

Therefore, the value for common factors is 10.

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 = 30485360159100/(1x10)

LCM = 30485360159100/10

LCM = 3048536015910

Thus, we can understand that the LCM of 397,505,253,742,810 is 3048536015910.
