Find LCM of 816,272,783 with Prime Factorization


2 816, 272, 783
2 408, 136, 783
2 204, 68, 783
2 102, 34, 783
3 51, 17, 783
17 17, 17, 261
1, 1, 261

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

2 x 2 x 2 x 2 x 3 x 17 x 1 x 1 x 261 = 212976

Therefore, the lowest common multiple of 816,272,783 is 212976.

LCM Formula to Find Lowest Common Multiple of 816,272,783

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.

816 x 272 x 783 = 173788416

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.

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

272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272

783 : 1, 3, 9, 27, 29, 87, 261, 783

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,272,783, is 1.

Now, the common factors can be found like this.

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

272:2x 2x 2x 2x 17

783:3x 3x 3x 29

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 3x 17 = 816

Therefore, the value for common factors is 816.

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 = 173788416/(1x816)

LCM = 173788416/816

LCM = 212976

Thus, we can understand that the LCM of 816,272,783 is 212976.
