Given numbers are 703,781,270,780

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

The LCM of 703,781,270,780 is 3854281860.

Find LCM of 703,781,270,780 with Prime Factorization

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

2 x 3 x 5 x 703 x 781 x 9 x 26 = 3854281860

Therefore, the lowest common multiple of 703,781,270,780 is 3854281860.

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.

703 x 781 x 270 x 780 = 115628455800

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.

703 : 1, 19, 37, 703

781 : 1, 11, 71, 781

270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 703,781,270,780, is 1.

Now, the common factors can be found like this.

703:19x 37

781:11x 71

270:2x 3x 3x 3x 5

780:2x 2x 3x 5x 13

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

2x 3x 5 = 30

Therefore, the value for common factors is 30.

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 = 115628455800/(1x30)

LCM = 115628455800/30

LCM = 3854281860

Thus, we can understand that the LCM of 703,781,270,780 is 3854281860.
