Given numbers are 780,635,145,865

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

The LCM of 780,635,145,865 is 496984020.

Find LCM of 780,635,145,865 with Prime Factorization

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

5 x 156 x 127 x 29 x 173 = 496984020

Therefore, the lowest common multiple of 780,635,145,865 is 496984020.

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 635 x 145 x 865 = 62123002500

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

635 : 1, 5, 127, 635

145 : 1, 5, 29, 145

865 : 1, 5, 173, 865

5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,635,145,865, is 5.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

635:5x 127

145:5x 29

865:5x 173

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 62123002500/(5x25)

LCM = 62123002500/125

LCM = 496984020

Thus, we can understand that the LCM of 780,635,145,865 is 496984020.
