Calculate the LCM of 445,356,803,988

Given numbers are 445,356,803,988

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

The LCM of 445,356,803,988 is 353046980.

Find LCM of 445,356,803,988 with Prime Factorization


2 445, 356, 803, 988
2 445, 178, 803, 494
89 445, 89, 803, 247
5, 1, 803, 247

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

2 x 2 x 89 x 5 x 1 x 803 x 247 = 353046980

Therefore, the lowest common multiple of 445,356,803,988 is 353046980.

LCM Formula to Find Lowest Common Multiple of 445,356,803,988

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.

445 x 356 x 803 x 988 = 125684724880

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.

445 : 1, 5, 89, 445

356 : 1, 2, 4, 89, 178, 356

803 : 1, 11, 73, 803

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 445,356,803,988, is 1.

Now, the common factors can be found like this.

445:5x 89

356:2x 2x 89

803:11x 73

988:2x 2x 13x 19

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 89 = 356

Therefore, the value for common factors is 356.

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 = 125684724880/(1x356)

LCM = 125684724880/356

LCM = 353046980

Thus, we can understand that the LCM of 445,356,803,988 is 353046980.
