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

2 x 2 x 2 x 3 x 18 x 179 x 649 x 323 x 91 = 1475113335696

Therefore, the lowest common multiple of 432,537,649,646,728 is 1475113335696.

LCM Formula to Find Lowest Common Multiple of 432,537,649,646,728

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.

432 x 537 x 649 x 646 x 728 = 70805440113408

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.

432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432

537 : 1, 3, 179, 537

649 : 1, 11, 59, 649

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

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 432,537,649,646,728, is 1.

Now, the common factors can be found like this.

432:2x 2x 2x 2x 3x 3x 3

537:3x 179

649:11x 59

646:2x 17x 19

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.

2x 2x 2x 2x 3 = 48

Therefore, the value for common factors is 48.

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 = 70805440113408/(1x48)

LCM = 70805440113408/48

LCM = 1475113335696

Thus, we can understand that the LCM of 432,537,649,646,728 is 1475113335696.
