Given numbers are 644,874,109,110,880

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

The LCM of 644,874,109,110,880 is 293419280.

Find LCM of 644,874,109,110,880 with Prime Factorization

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

2 x 2 x 5 x 11 x 23 x 7 x 19 x 109 x 1 x 4 = 293419280

Therefore, the lowest common multiple of 644,874,109,110,880 is 293419280.

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.

644 x 874 x 109 x 110 x 880 = 5938806227200

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.

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

874 : 1, 2, 19, 23, 38, 46, 437, 874

109 : 1, 109

110 : 1, 2, 5, 10, 11, 22, 55, 110

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,874,109,110,880, is 1.

Now, the common factors can be found like this.

644:2x 2x 7x 23

874:2x 19x 23

109:109

110:2x 5x 11

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

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 2x 5x 11x 23 = 20240

Therefore, the value for common factors is 20240.

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 = 5938806227200/(1x20240)

LCM = 5938806227200/20240

LCM = 293419280

Thus, we can understand that the LCM of 644,874,109,110,880 is 293419280.
