Given numbers are 781,556,215,473

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

The LCM of 781,556,215,473 is 93360740.

Find LCM of 781,556,215,473 with Prime Factorization

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

11 x 43 x 71 x 556 x 5 x 1 = 93360740

Therefore, the lowest common multiple of 781,556,215,473 is 93360740.

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.

781 x 556 x 215 x 473 = 44159630020

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.

781 : 1, 11, 71, 781

556 : 1, 2, 4, 139, 278, 556

215 : 1, 5, 43, 215

473 : 1, 11, 43, 473

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,556,215,473, is 1.

Now, the common factors can be found like this.

781:11x 71

556:2x 2x 139

215:5x 43

473:11x 43

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

11x 43 = 473

Therefore, the value for common factors is 473.

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 = 44159630020/(1x473)

LCM = 44159630020/473

LCM = 93360740

Thus, we can understand that the LCM of 781,556,215,473 is 93360740.
