Given numbers are 840,647,370,505,970

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

The LCM of 840,647,370,505,970 is 197005521720.

Find LCM of 840,647,370,505,970 with Prime Factorization

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

2 x 5 x 84 x 647 x 37 x 101 x 97 = 197005521720

Therefore, the lowest common multiple of 840,647,370,505,970 is 197005521720.

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.

840 x 647 x 370 x 505 x 970 = 98502760860000

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.

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

647 : 1, 647

370 : 1, 2, 5, 10, 37, 74, 185, 370

505 : 1, 5, 101, 505

970 : 1, 2, 5, 10, 97, 194, 485, 970

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,647,370,505,970, is 1.

Now, the common factors can be found like this.

840:2x 2x 2x 3x 5x 7

647:647

370:2x 5x 37

505:5x 101

970:2x 5x 97

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

2x 2x 5x 5x 5 = 500

Therefore, the value for common factors is 500.

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 = 98502760860000/(1x500)

LCM = 98502760860000/500

LCM = 197005521720

Thus, we can understand that the LCM of 840,647,370,505,970 is 197005521720.
