Calculate the LCM of 869,642,830,590

Given numbers are 869,642,830,590

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

The LCM of 869,642,830,590 is 13660132530.

Find LCM of 869,642,830,590 with Prime Factorization


2 869, 642, 830, 590
5 869, 321, 415, 295
869, 321, 83, 59

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

2 x 5 x 869 x 321 x 83 x 59 = 13660132530

Therefore, the lowest common multiple of 869,642,830,590 is 13660132530.

LCM Formula to Find Lowest Common Multiple of 869,642,830,590

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.

869 x 642 x 830 x 590 = 273202650600

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.

869 : 1, 11, 79, 869

642 : 1, 2, 3, 6, 107, 214, 321, 642

830 : 1, 2, 5, 10, 83, 166, 415, 830

590 : 1, 2, 5, 10, 59, 118, 295, 590

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 869,642,830,590, is 1.

Now, the common factors can be found like this.

869:11x 79

642:2x 3x 107

830:2x 5x 83

590:2x 5x 59

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 = 273202650600/(1x20)

LCM = 273202650600/20

LCM = 13660132530

Thus, we can understand that the LCM of 869,642,830,590 is 13660132530.
