Given numbers are 805,907,852,620,287

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

The LCM of 805,907,852,620,287 is 790657350420.

Find LCM of 805,907,852,620,287 with Prime Factorization


2 805, 907, 852, 620, 287
2 805, 907, 426, 310, 287
5 805, 907, 213, 155, 287
7 161, 907, 213, 31, 287
23, 907, 213, 31, 41

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

2 x 2 x 5 x 7 x 23 x 907 x 213 x 31 x 41 = 790657350420

Therefore, the lowest common multiple of 805,907,852,620,287 is 790657350420.

LCM Formula to Find Lowest Common Multiple of 805,907,852,620,287

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.

805 x 907 x 852 x 620 x 287 = 110692029058800

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.

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

907 : 1, 907

852 : 1, 2, 3, 4, 6, 12, 71, 142, 213, 284, 426, 852

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

287 : 1, 7, 41, 287

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 805,907,852,620,287, is 1.

Now, the common factors can be found like this.

805:5x 7x 23

907:907

852:2x 2x 3x 71

620:2x 2x 5x 31

287:7x 41

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

2x 2x 5x 7 = 140

Therefore, the value for common factors is 140.

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 = 110692029058800/(1x140)

LCM = 110692029058800/140

LCM = 790657350420

Thus, we can understand that the LCM of 805,907,852,620,287 is 790657350420.
