Given numbers are 161,690,783,213,457

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

The LCM of 161,690,783,213,457 is 40903661610.

Find LCM of 161,690,783,213,457 with Prime Factorization

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

3 x 23 x 7 x 10 x 261 x 71 x 457 = 40903661610

Therefore, the lowest common multiple of 161,690,783,213,457 is 40903661610.

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.

161 x 690 x 783 x 213 x 457 = 8467057953270

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.

161 : 1, 7, 23, 161

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

783 : 1, 3, 9, 27, 29, 87, 261, 783

213 : 1, 3, 71, 213

457 : 1, 457

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,690,783,213,457, is 1.

Now, the common factors can be found like this.

161:7x 23

690:2x 3x 5x 23

783:3x 3x 3x 29

213:3x 71

457:457

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

3x 3x 23 = 207

Therefore, the value for common factors is 207.

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 = 8467057953270/(1x207)

LCM = 8467057953270/207

LCM = 40903661610

Thus, we can understand that the LCM of 161,690,783,213,457 is 40903661610.
