Find LCM of 728,187,550,686,101 with Prime Factorization


2 728, 187, 550, 686, 101
7 364, 187, 275, 343, 101
11 52, 187, 275, 49, 101
52, 17, 25, 49, 101

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

2 x 7 x 11 x 52 x 17 x 25 x 49 x 101 = 16843426600

Therefore, the lowest common multiple of 728,187,550,686,101 is 16843426600.

LCM Formula to Find Lowest Common Multiple of 728,187,550,686,101

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.

728 x 187 x 550 x 686 x 101 = 5187775392800

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.

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

187 : 1, 11, 17, 187

550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550

686 : 1, 2, 7, 14, 49, 98, 343, 686

101 : 1, 101

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,187,550,686,101, is 1.

Now, the common factors can be found like this.

728:2x 2x 2x 7x 13

187:11x 17

550:2x 5x 5x 11

686:2x 7x 7x 7

101:101

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 7x 11 = 308

Therefore, the value for common factors is 308.

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 = 5187775392800/(1x308)

LCM = 5187775392800/308

LCM = 16843426600

Thus, we can understand that the LCM of 728,187,550,686,101 is 16843426600.
