Given numbers are 100,902,403,816,865

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

The LCM of 100,902,403,816,865 is 641442687600.

Find LCM of 100,902,403,816,865 with Prime Factorization

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

2 x 2 x 5 x 5 x 451 x 403 x 204 x 173 = 641442687600

Therefore, the lowest common multiple of 100,902,403,816,865 is 641442687600.

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.

100 x 902 x 403 x 816 x 865 = 25657707504000

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.

100 : 1, 2, 4, 5, 10, 20, 25, 50, 100

902 : 1, 2, 11, 22, 41, 82, 451, 902

403 : 1, 13, 31, 403

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

865 : 1, 5, 173, 865

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 100,902,403,816,865, is 1.

Now, the common factors can be found like this.

100:2x 2x 5x 5

902:2x 11x 41

403:13x 31

816:2x 2x 2x 2x 3x 17

865:5x 173

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 5 = 40

Therefore, the value for common factors is 40.

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 = 25657707504000/(1x40)

LCM = 25657707504000/40

LCM = 641442687600

Thus, we can understand that the LCM of 100,902,403,816,865 is 641442687600.
