Given numbers are 247,145,903,406

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

The LCM of 247,145,903,406 is 64681890.

Find LCM of 247,145,903,406 with Prime Factorization

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

7 x 29 x 247 x 5 x 129 x 2 = 64681890

Therefore, the lowest common multiple of 247,145,903,406 is 64681890.

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.

247 x 145 x 903 x 406 = 13130423670

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.

247 : 1, 13, 19, 247

145 : 1, 5, 29, 145

903 : 1, 3, 7, 21, 43, 129, 301, 903

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,145,903,406, is 1.

Now, the common factors can be found like this.

247:13x 19

145:5x 29

903:3x 7x 43

406:2x 7x 29

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

7x 29 = 203

Therefore, the value for common factors is 203.

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 = 13130423670/(1x203)

LCM = 13130423670/203

LCM = 64681890

Thus, we can understand that the LCM of 247,145,903,406 is 64681890.
