Given numbers are 421,287,245,829

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

The LCM of 421,287,245,829 is 3505795405.

Find LCM of 421,287,245,829 with Prime Factorization

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

7 x 421 x 41 x 35 x 829 = 3505795405

Therefore, the lowest common multiple of 421,287,245,829 is 3505795405.

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.

421 x 287 x 245 x 829 = 24540567835

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.

421 : 1, 421

287 : 1, 7, 41, 287

245 : 1, 5, 7, 35, 49, 245

829 : 1, 829

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,287,245,829, is 1.

Now, the common factors can be found like this.

421:421

287:7x 41

245:5x 7x 7

829:829

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

7 = 7

Therefore, the value for common factors is 7.

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 = 24540567835/(1x7)

LCM = 24540567835/7

LCM = 3505795405

Thus, we can understand that the LCM of 421,287,245,829 is 3505795405.
