Calculate the LCM of 689,870,681,529,899

Given numbers are 689,870,681,529,899

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

The LCM of 689,870,681,529,899 is 2231421933390.

Find LCM of 689,870,681,529,899 with Prime Factorization


3 689, 870, 681, 529, 899
29 689, 290, 227, 529, 899
689, 10, 227, 529, 31

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

3 x 29 x 689 x 10 x 227 x 529 x 31 = 2231421933390

Therefore, the lowest common multiple of 689,870,681,529,899 is 2231421933390.

LCM Formula to Find Lowest Common Multiple of 689,870,681,529,899

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.

689 x 870 x 681 x 529 x 899 = 194133708204930

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.

689 : 1, 13, 53, 689

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

681 : 1, 3, 227, 681

529 : 1, 23, 529

899 : 1, 29, 31, 899

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,870,681,529,899, is 1.

Now, the common factors can be found like this.

689:13x 53

870:2x 3x 5x 29

681:3x 227

529:23x 23

899:29x 31

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

3x 29 = 87

Therefore, the value for common factors is 87.

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 = 194133708204930/(1x87)

LCM = 194133708204930/87

LCM = 2231421933390

Thus, we can understand that the LCM of 689,870,681,529,899 is 2231421933390.
