Calculate the LCM of 180,904,686,391,859

Given numbers are 180,904,686,391,859

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

The LCM of 180,904,686,391,859 is 4686460765560.

Find LCM of 180,904,686,391,859 with Prime Factorization


2 180, 904, 686, 391, 859
2 90, 452, 343, 391, 859
45, 226, 343, 391, 859

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

2 x 2 x 45 x 226 x 343 x 391 x 859 = 4686460765560

Therefore, the lowest common multiple of 180,904,686,391,859 is 4686460765560.

LCM Formula to Find Lowest Common Multiple of 180,904,686,391,859

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.

180 x 904 x 686 x 391 x 859 = 37491686124480

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.

180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180

904 : 1, 2, 4, 8, 113, 226, 452, 904

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

391 : 1, 17, 23, 391

859 : 1, 859

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 180,904,686,391,859, is 1.

Now, the common factors can be found like this.

180:2x 2x 3x 3x 5

904:2x 2x 2x 113

686:2x 7x 7x 7

391:17x 23

859:859

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 2 = 8

Therefore, the value for common factors is 8.

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 = 37491686124480/(1x8)

LCM = 37491686124480/8

LCM = 4686460765560

Thus, we can understand that the LCM of 180,904,686,391,859 is 4686460765560.
