Given numbers are 860,780,497,779

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

The LCM of 860,780,497,779 is 12985447020.

Find LCM of 860,780,497,779 with Prime Factorization

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

2 x 2 x 5 x 43 x 39 x 497 x 779 = 12985447020

Therefore, the lowest common multiple of 860,780,497,779 is 12985447020.

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.

860 x 780 x 497 x 779 = 259708940400

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.

860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860

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

497 : 1, 7, 71, 497

779 : 1, 19, 41, 779

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 860,780,497,779, is 1.

Now, the common factors can be found like this.

860:2x 2x 5x 43

780:2x 2x 3x 5x 13

497:7x 71

779:19x 41

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 5 = 20

Therefore, the value for common factors is 20.

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 = 259708940400/(1x20)

LCM = 259708940400/20

LCM = 12985447020

Thus, we can understand that the LCM of 860,780,497,779 is 12985447020.
