Calculate the LCM of 868,398,805,493,247

Given numbers are 868,398,805,493,247

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

The LCM of 868,398,805,493,247 is 2418881062780.

Find LCM of 868,398,805,493,247 with Prime Factorization


2 868, 398, 805, 493, 247
7 434, 199, 805, 493, 247
62, 199, 115, 493, 247

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

2 x 7 x 62 x 199 x 115 x 493 x 247 = 2418881062780

Therefore, the lowest common multiple of 868,398,805,493,247 is 2418881062780.

LCM Formula to Find Lowest Common Multiple of 868,398,805,493,247

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.

868 x 398 x 805 x 493 x 247 = 33864334878920

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.

868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868

398 : 1, 2, 199, 398

805 : 1, 5, 7, 23, 35, 115, 161, 805

493 : 1, 17, 29, 493

247 : 1, 13, 19, 247

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 868,398,805,493,247, is 1.

Now, the common factors can be found like this.

868:2x 2x 7x 31

398:2x 199

805:5x 7x 23

493:17x 29

247:13x 19

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 33864334878920/(1x14)

LCM = 33864334878920/14

LCM = 2418881062780

Thus, we can understand that the LCM of 868,398,805,493,247 is 2418881062780.
