Given numbers are 421,861,947,404,982

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

The LCM of 421,861,947,404,982 is 68092312486548.

Find LCM of 421,861,947,404,982 with Prime Factorization

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

2 x 421 x 861 x 947 x 202 x 491 = 68092312486548

Therefore, the lowest common multiple of 421,861,947,404,982 is 68092312486548.

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 861 x 947 x 404 x 982 = 136184624973096

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

861 : 1, 3, 7, 21, 41, 123, 287, 861

947 : 1, 947

404 : 1, 2, 4, 101, 202, 404

982 : 1, 2, 491, 982

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,861,947,404,982, is 1.

Now, the common factors can be found like this.

421:421

861:3x 7x 41

947:947

404:2x 2x 101

982:2x 491

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

2 = 2

Therefore, the value for common factors is 2.

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 = 136184624973096/(1x2)

LCM = 136184624973096/2

LCM = 68092312486548

Thus, we can understand that the LCM of 421,861,947,404,982 is 68092312486548.
