Given numbers are 905,305,907,210

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

The LCM of 905,305,907,210 is 2102979270.

Find LCM of 905,305,907,210 with Prime Factorization

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

5 x 181 x 61 x 907 x 42 = 2102979270

Therefore, the lowest common multiple of 905,305,907,210 is 2102979270.

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 305 x 907 x 210 = 52574481750

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

305 : 1, 5, 61, 305

907 : 1, 907

210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 905,305,907,210, is 1.

Now, the common factors can be found like this.

905:5x 181

305:5x 61

907:907

210:2x 3x 5x 7

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 52574481750/(1x25)

LCM = 52574481750/25

LCM = 2102979270

Thus, we can understand that the LCM of 905,305,907,210 is 2102979270.
