Given numbers are 427,745,888,720

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

The LCM of 427,745,888,720 is 1694916720.

Find LCM of 427,745,888,720 with Prime Factorization

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

2 x 2 x 2 x 3 x 5 x 427 x 149 x 37 x 6 = 1694916720

Therefore, the lowest common multiple of 427,745,888,720 is 1694916720.

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.

427 x 745 x 888 x 720 = 203390006400

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.

427 : 1, 7, 61, 427

745 : 1, 5, 149, 745

888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 427,745,888,720, is 1.

Now, the common factors can be found like this.

427:7x 61

745:5x 149

888:2x 2x 2x 3x 37

720:2x 2x 2x 2x 3x 3x 5

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 3x 5 = 120

Therefore, the value for common factors is 120.

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 = 203390006400/(1x120)

LCM = 203390006400/120

LCM = 1694916720

Thus, we can understand that the LCM of 427,745,888,720 is 1694916720.
