Given numbers are 628,314,193,661

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

The LCM of 628,314,193,661 is 80115844.

Find LCM of 628,314,193,661 with Prime Factorization

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

2 x 157 x 2 x 1 x 193 x 661 = 80115844

Therefore, the lowest common multiple of 628,314,193,661 is 80115844.

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.

628 x 314 x 193 x 661 = 25156375016

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.

628 : 1, 2, 4, 157, 314, 628

314 : 1, 2, 157, 314

193 : 1, 193

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,314,193,661, is 1.

Now, the common factors can be found like this.

628:2x 2x 157

314:2x 157

193:193

661:661

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

2x 157 = 314

Therefore, the value for common factors is 314.

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 = 25156375016/(1x314)

LCM = 25156375016/314

LCM = 80115844

Thus, we can understand that the LCM of 628,314,193,661 is 80115844.
