LCM of:

Calculate the LCM of 880,689,580,890

Given numbers are 880,689,580,890

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

The LCM of 880,689,580,890 is 1564911920.

Find LCM of 880,689,580,890 with Prime Factorization


2 880, 689, 580, 890
2 440, 689, 290, 445
5 220, 689, 145, 445
44, 689, 29, 89

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

2 x 2 x 5 x 44 x 689 x 29 x 89 = 1564911920

Therefore, the lowest common multiple of 880,689,580,890 is 1564911920.

LCM Formula to Find Lowest Common Multiple of 880,689,580,890

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.

880 x 689 x 580 x 890 = 312982384000

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.

880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880

689 : 1, 13, 53, 689

580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580

890 : 1, 2, 5, 10, 89, 178, 445, 890

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 880,689,580,890, is 1.

Now, the common factors can be found like this.

880:2x 2x 2x 2x 5x 11

689:13x 53

580:2x 2x 5x 29

890:2x 5x 89

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 2x 5x 5 = 200

Therefore, the value for common factors is 200.

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 = 312982384000/(1x200)

LCM = 312982384000/200

LCM = 1564911920

Thus, we can understand that the LCM of 880,689,580,890 is 1564911920.
