Given numbers are 281,551,697,920,770

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

The LCM of 281,551,697,920,770 is 7644854943880.

Find LCM of 281,551,697,920,770 with Prime Factorization

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

2 x 5 x 281 x 551 x 697 x 92 x 77 = 7644854943880

Therefore, the lowest common multiple of 281,551,697,920,770 is 7644854943880.

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.

281 x 551 x 697 x 920 x 770 = 76448549438800

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.

281 : 1, 281

551 : 1, 19, 29, 551

697 : 1, 17, 41, 697

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,551,697,920,770, is 1.

Now, the common factors can be found like this.

281:281

551:19x 29

697:17x 41

920:2x 2x 2x 5x 23

770:2x 5x 7x 11

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 = 76448549438800/(1x10)

LCM = 76448549438800/10

LCM = 7644854943880

Thus, we can understand that the LCM of 281,551,697,920,770 is 7644854943880.
