Given numbers are 637,715,223,394

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

The LCM of 637,715,223,394 is 3078245170.

Find LCM of 637,715,223,394 with Prime Factorization

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

13 x 49 x 55 x 223 x 394 = 3078245170

Therefore, the lowest common multiple of 637,715,223,394 is 3078245170.

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.

637 x 715 x 223 x 394 = 40017187210

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.

637 : 1, 7, 13, 49, 91, 637

715 : 1, 5, 11, 13, 55, 65, 143, 715

223 : 1, 223

394 : 1, 2, 197, 394

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,715,223,394, is 1.

Now, the common factors can be found like this.

637:7x 7x 13

715:5x 11x 13

223:223

394:2x 197

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

13 = 13

Therefore, the value for common factors is 13.

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 = 40017187210/(1x13)

LCM = 40017187210/13

LCM = 3078245170

Thus, we can understand that the LCM of 637,715,223,394 is 3078245170.
