The LCM of 806,902,889,680 is 109873323560.

Find LCM of 806,902,889,680 with Prime Factorization


2 806, 902, 889, 680
403, 451, 889, 340

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

2 x 403 x 451 x 889 x 340 = 109873323560

Therefore, the lowest common multiple of 806,902,889,680 is 109873323560.

LCM Formula to Find Lowest Common Multiple of 806,902,889,680

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.

806 x 902 x 889 x 680 = 439493294240

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.

806 : 1, 2, 13, 26, 31, 62, 403, 806

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

889 : 1, 7, 127, 889

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 806,902,889,680, is 1.

Now, the common factors can be found like this.

806:2x 13x 31

902:2x 11x 41

889:7x 127

680:2x 2x 2x 5x 17

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 439493294240/(1x4)

LCM = 439493294240/4

LCM = 109873323560

Thus, we can understand that the LCM of 806,902,889,680 is 109873323560.
