Find LCM of 646,752,289,464 with Prime Factorization


2 646, 752, 289, 464
2 323, 376, 289, 232
2 323, 188, 289, 116
2 323, 94, 289, 58
17 323, 47, 289, 29
19, 47, 17, 29

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

2 x 2 x 2 x 2 x 17 x 19 x 47 x 17 x 29 = 119747728

Therefore, the lowest common multiple of 646,752,289,464 is 119747728.

LCM Formula to Find Lowest Common Multiple of 646,752,289,464

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.

646 x 752 x 289 x 464 = 65142764032

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.

646 : 1, 2, 17, 19, 34, 38, 323, 646

752 : 1, 2, 4, 8, 16, 47, 94, 188, 376, 752

289 : 1, 17, 289

464 : 1, 2, 4, 8, 16, 29, 58, 116, 232, 464

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,752,289,464, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

752:2x 2x 2x 2x 47

289:17x 17

464:2x 2x 2x 2x 29

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 2x 2x 2x 17 = 544

Therefore, the value for common factors is 544.

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 = 65142764032/(1x544)

LCM = 65142764032/544

LCM = 119747728

Thus, we can understand that the LCM of 646,752,289,464 is 119747728.
