Calculate the LCM of 330,308,781,446

Given numbers are 330,308,781,446

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

The LCM of 330,308,781,446 is 73148460.

Find LCM of 330,308,781,446 with Prime Factorization


2 330, 308, 781, 446
11 165, 154, 781, 223
15, 14, 71, 223

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

2 x 11 x 15 x 14 x 71 x 223 = 73148460

Therefore, the lowest common multiple of 330,308,781,446 is 73148460.

LCM Formula to Find Lowest Common Multiple of 330,308,781,446

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.

330 x 308 x 781 x 446 = 35403854640

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.

330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330

308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308

781 : 1, 11, 71, 781

446 : 1, 2, 223, 446

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 330,308,781,446, is 1.

Now, the common factors can be found like this.

330:2x 3x 5x 11

308:2x 2x 7x 11

781:11x 71

446:2x 223

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 11x 11 = 484

Therefore, the value for common factors is 484.

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 = 35403854640/(1x484)

LCM = 35403854640/484

LCM = 73148460

Thus, we can understand that the LCM of 330,308,781,446 is 73148460.
