Calculate the LCM of 365,285,355,781

Given numbers are 365,285,355,781

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

The LCM of 365,285,355,781 is 16248705.

Find LCM of 365,285,355,781 with Prime Factorization


5 365, 285, 355, 781
71 73, 57, 71, 781
73, 57, 1, 11

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

5 x 71 x 73 x 57 x 1 x 11 = 16248705

Therefore, the lowest common multiple of 365,285,355,781 is 16248705.

LCM Formula to Find Lowest Common Multiple of 365,285,355,781

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.

365 x 285 x 355 x 781 = 28841451375

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.

365 : 1, 5, 73, 365

285 : 1, 3, 5, 15, 19, 57, 95, 285

355 : 1, 5, 71, 355

781 : 1, 11, 71, 781

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 365,285,355,781, is 1.

Now, the common factors can be found like this.

365:5x 73

285:3x 5x 19

355:5x 71

781:11x 71

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

5x 5x 71 = 1775

Therefore, the value for common factors is 1775.

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 = 28841451375/(1x1775)

LCM = 28841451375/1775

LCM = 16248705

Thus, we can understand that the LCM of 365,285,355,781 is 16248705.
