Calculate the LCM of 805,101,660,290

Given numbers are 805,101,660,290

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

The LCM of 805,101,660,290 is 311235540.

Find LCM of 805,101,660,290 with Prime Factorization


2 805, 101, 660, 290
5 805, 101, 330, 145
161, 101, 66, 29

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

2 x 5 x 161 x 101 x 66 x 29 = 311235540

Therefore, the lowest common multiple of 805,101,660,290 is 311235540.

LCM Formula to Find Lowest Common Multiple of 805,101,660,290

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 101 x 660 x 290 = 15561777000

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

101 : 1, 101

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

290 : 1, 2, 5, 10, 29, 58, 145, 290

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 805,101,660,290, is 1.

Now, the common factors can be found like this.

805:5x 7x 23

101:101

660:2x 2x 3x 5x 11

290:2x 5x 29

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

2x 5x 5 = 50

Therefore, the value for common factors is 50.

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 = 15561777000/(1x50)

LCM = 15561777000/50

LCM = 311235540

Thus, we can understand that the LCM of 805,101,660,290 is 311235540.
