Find LCM of 742,363,321,803,642 with Prime Factorization


2 742, 363, 321, 803, 642
3 371, 363, 321, 803, 321
11 371, 121, 107, 803, 107
107 371, 11, 107, 73, 107
371, 11, 1, 73, 1

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

2 x 3 x 11 x 107 x 371 x 11 x 1 x 73 x 1 = 2103861606

Therefore, the lowest common multiple of 742,363,321,803,642 is 2103861606.

LCM Formula to Find Lowest Common Multiple of 742,363,321,803,642

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.

742 x 363 x 321 x 803 x 642 = 44572411984716

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.

742 : 1, 2, 7, 14, 53, 106, 371, 742

363 : 1, 3, 11, 33, 121, 363

321 : 1, 3, 107, 321

803 : 1, 11, 73, 803

642 : 1, 2, 3, 6, 107, 214, 321, 642

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 742,363,321,803,642, is 1.

Now, the common factors can be found like this.

742:2x 7x 53

363:3x 11x 11

321:3x 107

803:11x 73

642:2x 3x 107

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

2x 3x 3x 11x 107 = 21186

Therefore, the value for common factors is 21186.

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 = 44572411984716/(1x21186)

LCM = 44572411984716/21186

LCM = 2103861606

Thus, we can understand that the LCM of 742,363,321,803,642 is 2103861606.
