Calculate the LCM of 276,560,242,780

Given numbers are 276,560,242,780

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

The LCM of 276,560,242,780 is 60780720.

Find LCM of 276,560,242,780 with Prime Factorization


2 276, 560, 242, 780
2 138, 280, 121, 390
3 69, 140, 121, 195
5 23, 140, 121, 65
23, 28, 121, 13

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

2 x 2 x 3 x 5 x 23 x 28 x 121 x 13 = 60780720

Therefore, the lowest common multiple of 276,560,242,780 is 60780720.

LCM Formula to Find Lowest Common Multiple of 276,560,242,780

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.

276 x 560 x 242 x 780 = 29174745600

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.

276 : 1, 2, 3, 4, 6, 12, 23, 46, 69, 92, 138, 276

560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560

242 : 1, 2, 11, 22, 121, 242

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 276,560,242,780, is 2.

Now, the common factors can be found like this.

276:2x 2x 3x 23

560:2x 2x 2x 2x 5x 7

242:2x 11x 11

780:2x 2x 3x 5x 13

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 5 = 240

Therefore, the value for common factors is 240.

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 = 29174745600/(2x240)

LCM = 29174745600/480

LCM = 60780720

Thus, we can understand that the LCM of 276,560,242,780 is 60780720.
