Given numbers are 641,706,353,247

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

The LCM of 641,706,353,247 is 111778862.

Find LCM of 641,706,353,247 with Prime Factorization

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

353 x 641 x 2 x 1 x 247 = 111778862

Therefore, the lowest common multiple of 641,706,353,247 is 111778862.

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.

641 x 706 x 353 x 247 = 39457938286

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.

641 : 1, 641

706 : 1, 2, 353, 706

353 : 1, 353

247 : 1, 13, 19, 247

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,706,353,247, is 1.

Now, the common factors can be found like this.

641:641

706:2x 353

353:353

247:13x 19

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

353 = 353

Therefore, the value for common factors is 353.

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 = 39457938286/(1x353)

LCM = 39457938286/353

LCM = 111778862

Thus, we can understand that the LCM of 641,706,353,247 is 111778862.
