Calculate the LCM of 435,205,677,728

Given numbers are 435,205,677,728

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

The LCM of 435,205,677,728 is 8790086760.

Find LCM of 435,205,677,728 with Prime Factorization


5 435, 205, 677, 728
87, 41, 677, 728

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

5 x 87 x 41 x 677 x 728 = 8790086760

Therefore, the lowest common multiple of 435,205,677,728 is 8790086760.

LCM Formula to Find Lowest Common Multiple of 435,205,677,728

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.

435 x 205 x 677 x 728 = 43950433800

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.

435 : 1, 3, 5, 15, 29, 87, 145, 435

205 : 1, 5, 41, 205

677 : 1, 677

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 435,205,677,728, is 1.

Now, the common factors can be found like this.

435:3x 5x 29

205:5x 41

677:677

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.

5 = 5

Therefore, the value for common factors is 5.

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 = 43950433800/(1x5)

LCM = 43950433800/5

LCM = 8790086760

Thus, we can understand that the LCM of 435,205,677,728 is 8790086760.
