Given numbers are 662,905,817,20

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

The LCM of 662,905,817,20 is 978945740.

Find LCM of 662,905,817,20 with Prime Factorization

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

2 x 5 x 331 x 181 x 817 x 2 = 978945740

Therefore, the lowest common multiple of 662,905,817,20 is 978945740.

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.

662 x 905 x 817 x 20 = 9789457400

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.

662 : 1, 2, 331, 662

905 : 1, 5, 181, 905

817 : 1, 19, 43, 817

20 : 1, 2, 4, 5, 10, 20

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 662,905,817,20, is 1.

Now, the common factors can be found like this.

662:2x 331

905:5x 181

817:19x 43

20:2x 2x 5

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 9789457400/(1x10)

LCM = 9789457400/10

LCM = 978945740

Thus, we can understand that the LCM of 662,905,817,20 is 978945740.
