Given numbers are 905,351,947,403

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

The LCM of 905,351,947,403 is 9325397835.

Find LCM of 905,351,947,403 with Prime Factorization

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

13 x 905 x 27 x 947 x 31 = 9325397835

Therefore, the lowest common multiple of 905,351,947,403 is 9325397835.

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.

905 x 351 x 947 x 403 = 121230171855

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.

905 : 1, 5, 181, 905

351 : 1, 3, 9, 13, 27, 39, 117, 351

947 : 1, 947

403 : 1, 13, 31, 403

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 905,351,947,403, is 1.

Now, the common factors can be found like this.

905:5x 181

351:3x 3x 3x 13

947:947

403:13x 31

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

13 = 13

Therefore, the value for common factors is 13.

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 = 121230171855/(1x13)

LCM = 121230171855/13

LCM = 9325397835

Thus, we can understand that the LCM of 905,351,947,403 is 9325397835.
