Calculate the LCM of 870,671,395,854

Given numbers are 870,671,395,854

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

The LCM of 870,671,395,854 is 322824810.

Find LCM of 870,671,395,854 with Prime Factorization


2 870, 671, 395, 854
5 435, 671, 395, 427
61 87, 671, 79, 427
87, 11, 79, 7

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

2 x 5 x 61 x 87 x 11 x 79 x 7 = 322824810

Therefore, the lowest common multiple of 870,671,395,854 is 322824810.

LCM Formula to Find Lowest Common Multiple of 870,671,395,854

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.

870 x 671 x 395 x 854 = 196923134100

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.

870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870

671 : 1, 11, 61, 671

395 : 1, 5, 79, 395

854 : 1, 2, 7, 14, 61, 122, 427, 854

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 870,671,395,854, is 1.

Now, the common factors can be found like this.

870:2x 3x 5x 29

671:11x 61

395:5x 79

854:2x 7x 61

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 61 = 610

Therefore, the value for common factors is 610.

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 = 196923134100/(1x610)

LCM = 196923134100/610

LCM = 322824810

Thus, we can understand that the LCM of 870,671,395,854 is 322824810.
