Calculate the LCM of 391,411,156,281,281

Given numbers are 391,411,156,281,281

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

The LCM of 391,411,156,281,281 is 2348163012.

Find LCM of 391,411,156,281,281 with Prime Factorization


3 391, 411, 156, 281, 281
281 391, 137, 52, 281, 281
391, 137, 52, 1, 1

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

3 x 281 x 391 x 137 x 52 x 1 x 1 = 2348163012

Therefore, the lowest common multiple of 391,411,156,281,281 is 2348163012.

LCM Formula to Find Lowest Common Multiple of 391,411,156,281,281

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.

391 x 411 x 156 x 281 x 281 = 1979501419116

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.

391 : 1, 17, 23, 391

411 : 1, 3, 137, 411

156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156

281 : 1, 281

281 : 1, 281

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,411,156,281,281, is 1.

Now, the common factors can be found like this.

391:17x 23

411:3x 137

156:2x 2x 3x 13

281:281

281:281

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

3x 281 = 843

Therefore, the value for common factors is 843.

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 = 1979501419116/(1x843)

LCM = 1979501419116/843

LCM = 2348163012

Thus, we can understand that the LCM of 391,411,156,281,281 is 2348163012.
