Calculate the LCM of 290,686,491,480

Given numbers are 290,686,491,480

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

The LCM of 290,686,491,480 is 2344308960.

Find LCM of 290,686,491,480 with Prime Factorization


2 290, 686, 491, 480
5 145, 343, 491, 240
29, 343, 491, 48

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

2 x 5 x 29 x 343 x 491 x 48 = 2344308960

Therefore, the lowest common multiple of 290,686,491,480 is 2344308960.

LCM Formula to Find Lowest Common Multiple of 290,686,491,480

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.

290 x 686 x 491 x 480 = 46886179200

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.

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

686 : 1, 2, 7, 14, 49, 98, 343, 686

491 : 1, 491

480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 290,686,491,480, is 1.

Now, the common factors can be found like this.

290:2x 5x 29

686:2x 7x 7x 7

491:491

480:2x 2x 2x 2x 2x 3x 5

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 5 = 20

Therefore, the value for common factors is 20.

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 = 46886179200/(1x20)

LCM = 46886179200/20

LCM = 2344308960

Thus, we can understand that the LCM of 290,686,491,480 is 2344308960.
