Given numbers are 661,391,437,194

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

The LCM of 661,391,437,194 is 952650386.

Find LCM of 661,391,437,194 with Prime Factorization

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

23 x 661 x 17 x 19 x 194 = 952650386

Therefore, the lowest common multiple of 661,391,437,194 is 952650386.

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 391 x 437 x 194 = 21910958878

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

391 : 1, 17, 23, 391

437 : 1, 19, 23, 437

194 : 1, 2, 97, 194

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,391,437,194, is 1.

Now, the common factors can be found like this.

661:661

391:17x 23

437:19x 23

194:2x 97

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

23 = 23

Therefore, the value for common factors is 23.

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 = 21910958878/(1x23)

LCM = 21910958878/23

LCM = 952650386

Thus, we can understand that the LCM of 661,391,437,194 is 952650386.
