Calculate the LCM of 245,440,461,885

Given numbers are 245,440,461,885

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

The LCM of 245,440,461,885 is 1759231320.

Find LCM of 245,440,461,885 with Prime Factorization


5 245, 440, 461, 885
49, 88, 461, 177

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

5 x 49 x 88 x 461 x 177 = 1759231320

Therefore, the lowest common multiple of 245,440,461,885 is 1759231320.

LCM Formula to Find Lowest Common Multiple of 245,440,461,885

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.

245 x 440 x 461 x 885 = 43980783000

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.

245 : 1, 5, 7, 35, 49, 245

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

461 : 1, 461

885 : 1, 3, 5, 15, 59, 177, 295, 885

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 245,440,461,885, is 1.

Now, the common factors can be found like this.

245:5x 7x 7

440:2x 2x 2x 5x 11

461:461

885:3x 5x 59

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 43980783000/(1x25)

LCM = 43980783000/25

LCM = 1759231320

Thus, we can understand that the LCM of 245,440,461,885 is 1759231320.
