Calculate the LCM of 728,669,478,734

Given numbers are 728,669,478,734

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

The LCM of 728,669,478,734 is 42719037816.

Find LCM of 728,669,478,734 with Prime Factorization


2 728, 669, 478, 734
364, 669, 239, 367

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

2 x 364 x 669 x 239 x 367 = 42719037816

Therefore, the lowest common multiple of 728,669,478,734 is 42719037816.

LCM Formula to Find Lowest Common Multiple of 728,669,478,734

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.

728 x 669 x 478 x 734 = 170876151264

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.

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

669 : 1, 3, 223, 669

478 : 1, 2, 239, 478

734 : 1, 2, 367, 734

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,669,478,734, is 1.

Now, the common factors can be found like this.

728:2x 2x 2x 7x 13

669:3x 223

478:2x 239

734:2x 367

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 170876151264/(1x4)

LCM = 170876151264/4

LCM = 42719037816

Thus, we can understand that the LCM of 728,669,478,734 is 42719037816.
