Calculate the LCM of 210,286,722,816

Given numbers are 210,286,722,816

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

The LCM of 210,286,722,816 is 1474352880.

Find LCM of 210,286,722,816 with Prime Factorization


2 210, 286, 722, 816
3 105, 143, 361, 408
35, 143, 361, 136

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

2 x 3 x 35 x 143 x 361 x 136 = 1474352880

Therefore, the lowest common multiple of 210,286,722,816 is 1474352880.

LCM Formula to Find Lowest Common Multiple of 210,286,722,816

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.

210 x 286 x 722 x 816 = 35384469120

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.

210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210

286 : 1, 2, 11, 13, 22, 26, 143, 286

722 : 1, 2, 19, 38, 361, 722

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 210,286,722,816, is 2.

Now, the common factors can be found like this.

210:2x 3x 5x 7

286:2x 11x 13

722:2x 19x 19

816:2x 2x 2x 2x 3x 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 2x 3 = 12

Therefore, the value for common factors is 12.

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 = 35384469120/(2x12)

LCM = 35384469120/24

LCM = 1474352880

Thus, we can understand that the LCM of 210,286,722,816 is 1474352880.
