The LCM of 642,943,335,728 is 73823207640.

Find LCM of 642,943,335,728 with Prime Factorization


2 642, 943, 335, 728
321, 943, 335, 364

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

2 x 321 x 943 x 335 x 364 = 73823207640

Therefore, the lowest common multiple of 642,943,335,728 is 73823207640.

LCM Formula to Find Lowest Common Multiple of 642,943,335,728

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.

642 x 943 x 335 x 728 = 147646415280

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.

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

943 : 1, 23, 41, 943

335 : 1, 5, 67, 335

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,943,335,728, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

943:23x 41

335:5x 67

728:2x 2x 2x 7x 13

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

2 = 2

Therefore, the value for common factors is 2.

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 = 147646415280/(1x2)

LCM = 147646415280/2

LCM = 73823207640

Thus, we can understand that the LCM of 642,943,335,728 is 73823207640.
