Given numbers are 972,149,780,717

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

The LCM of 972,149,780,717 is 2249902980.

Find LCM of 972,149,780,717 with Prime Factorization

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

2 x 2 x 3 x 81 x 149 x 65 x 239 = 2249902980

Therefore, the lowest common multiple of 972,149,780,717 is 2249902980.

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.

972 x 149 x 780 x 717 = 80996507280

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.

972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972

149 : 1, 149

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

717 : 1, 3, 239, 717

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 972,149,780,717, is 1.

Now, the common factors can be found like this.

972:2x 2x 3x 3x 3x 3x 3

149:149

780:2x 2x 3x 5x 13

717:3x 239

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 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 80996507280/(1x36)

LCM = 80996507280/36

LCM = 2249902980

Thus, we can understand that the LCM of 972,149,780,717 is 2249902980.
