Calculate the LCM of 648,299,400,281

Given numbers are 648,299,400,281

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

The LCM of 648,299,400,281 is 2722215600.

Find LCM of 648,299,400,281 with Prime Factorization


2 648, 299, 400, 281
2 324, 299, 200, 281
2 162, 299, 100, 281
81, 299, 50, 281

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

2 x 2 x 2 x 81 x 299 x 50 x 281 = 2722215600

Therefore, the lowest common multiple of 648,299,400,281 is 2722215600.

LCM Formula to Find Lowest Common Multiple of 648,299,400,281

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.

648 x 299 x 400 x 281 = 21777724800

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.

648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648

299 : 1, 13, 23, 299

400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400

281 : 1, 281

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 648,299,400,281, is 1.

Now, the common factors can be found like this.

648:2x 2x 2x 3x 3x 3x 3

299:13x 23

400:2x 2x 2x 2x 5x 5

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.

2x 2x 2 = 8

Therefore, the value for common factors is 8.

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 = 21777724800/(1x8)

LCM = 21777724800/8

LCM = 2722215600

Thus, we can understand that the LCM of 648,299,400,281 is 2722215600.
