Given numbers are 780,252,939,673,639

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

The LCM of 780,252,939,673,639 is 244980574020.

Find LCM of 780,252,939,673,639 with Prime Factorization

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

2 x 2 x 3 x 3 x 65 x 7 x 313 x 673 x 71 = 244980574020

Therefore, the lowest common multiple of 780,252,939,673,639 is 244980574020.

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.

780 x 252 x 939 x 673 x 639 = 79373705982480

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.

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

252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252

939 : 1, 3, 313, 939

673 : 1, 673

639 : 1, 3, 9, 71, 213, 639

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,252,939,673,639, is 1.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

252:2x 2x 3x 3x 7

939:3x 313

673:673

639:3x 3x 71

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 3x 3x 3 = 324

Therefore, the value for common factors is 324.

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 = 79373705982480/(1x324)

LCM = 79373705982480/324

LCM = 244980574020

Thus, we can understand that the LCM of 780,252,939,673,639 is 244980574020.
