Given numbers are 432,771,178,715

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

The LCM of 432,771,178,715 is 7065012240.

Find LCM of 432,771,178,715 with Prime Factorization

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

2 x 3 x 72 x 257 x 89 x 715 = 7065012240

Therefore, the lowest common multiple of 432,771,178,715 is 7065012240.

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 771 x 178 x 715 = 42390073440

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

771 : 1, 3, 257, 771

178 : 1, 2, 89, 178

715 : 1, 5, 11, 13, 55, 65, 143, 715

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 432,771,178,715, is 1.

Now, the common factors can be found like this.

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

771:3x 257

178:2x 89

715:5x 11x 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 3 = 6

Therefore, the value for common factors is 6.

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 = 42390073440/(1x6)

LCM = 42390073440/6

LCM = 7065012240

Thus, we can understand that the LCM of 432,771,178,715 is 7065012240.
