Calculate the LCM of 281,789,862,480

Given numbers are 281,789,862,480

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

The LCM of 281,789,862,480 is 15289052640.

Find LCM of 281,789,862,480 with Prime Factorization


2 281, 789, 862, 480
3 281, 789, 431, 240
281, 263, 431, 80

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

2 x 3 x 281 x 263 x 431 x 80 = 15289052640

Therefore, the lowest common multiple of 281,789,862,480 is 15289052640.

LCM Formula to Find Lowest Common Multiple of 281,789,862,480

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.

281 x 789 x 862 x 480 = 91734315840

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.

281 : 1, 281

789 : 1, 3, 263, 789

862 : 1, 2, 431, 862

480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,789,862,480, is 1.

Now, the common factors can be found like this.

281:281

789:3x 263

862:2x 431

480:2x 2x 2x 2x 2x 3x 5

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 91734315840/(1x6)

LCM = 91734315840/6

LCM = 15289052640

Thus, we can understand that the LCM of 281,789,862,480 is 15289052640.
