Given numbers are 899,406,947,720,394

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

The LCM of 899,406,947,720,394 is 845291366640.

Find LCM of 899,406,947,720,394 with Prime Factorization

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

2 x 29 x 31 x 7 x 947 x 360 x 197 = 845291366640

Therefore, the lowest common multiple of 899,406,947,720,394 is 845291366640.

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.

899 x 406 x 947 x 720 x 394 = 98053798530240

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.

899 : 1, 29, 31, 899

406 : 1, 2, 7, 14, 29, 58, 203, 406

947 : 1, 947

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

394 : 1, 2, 197, 394

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 899,406,947,720,394, is 1.

Now, the common factors can be found like this.

899:29x 31

406:2x 7x 29

947:947

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

394:2x 197

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 29 = 116

Therefore, the value for common factors is 116.

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 = 98053798530240/(1x116)

LCM = 98053798530240/116

LCM = 845291366640

Thus, we can understand that the LCM of 899,406,947,720,394 is 845291366640.
