Given numbers are 909,472,781,538,857

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

The LCM of 909,472,781,538,857 is 77248493338104.

Find LCM of 909,472,781,538,857 with Prime Factorization

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

2 x 909 x 236 x 781 x 269 x 857 = 77248493338104

Therefore, the lowest common multiple of 909,472,781,538,857 is 77248493338104.

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.

909 x 472 x 781 x 538 x 857 = 154496986676208

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.

909 : 1, 3, 9, 101, 303, 909

472 : 1, 2, 4, 8, 59, 118, 236, 472

781 : 1, 11, 71, 781

538 : 1, 2, 269, 538

857 : 1, 857

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 909,472,781,538,857, is 1.

Now, the common factors can be found like this.

909:3x 3x 101

472:2x 2x 2x 59

781:11x 71

538:2x 269

857:857

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

2 = 2

Therefore, the value for common factors is 2.

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 = 154496986676208/(1x2)

LCM = 154496986676208/2

LCM = 77248493338104

Thus, we can understand that the LCM of 909,472,781,538,857 is 77248493338104.
