Given numbers are 661,273,143,473

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

The LCM of 661,273,143,473 is 85354269.

Find LCM of 661,273,143,473 with Prime Factorization

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

11 x 13 x 661 x 21 x 1 x 43 = 85354269

Therefore, the lowest common multiple of 661,273,143,473 is 85354269.

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.

661 x 273 x 143 x 473 = 12205660467

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.

661 : 1, 661

273 : 1, 3, 7, 13, 21, 39, 91, 273

143 : 1, 11, 13, 143

473 : 1, 11, 43, 473

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,273,143,473, is 1.

Now, the common factors can be found like this.

661:661

273:3x 7x 13

143:11x 13

473:11x 43

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

11x 13 = 143

Therefore, the value for common factors is 143.

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 = 12205660467/(1x143)

LCM = 12205660467/143

LCM = 85354269

Thus, we can understand that the LCM of 661,273,143,473 is 85354269.
