Given numbers are 869,122,643,781

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

The LCM of 869,122,643,781 is 4840039754.

Find LCM of 869,122,643,781 with Prime Factorization

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

11 x 79 x 122 x 643 x 71 = 4840039754

Therefore, the lowest common multiple of 869,122,643,781 is 4840039754.

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.

869 x 122 x 643 x 781 = 53240437294

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.

869 : 1, 11, 79, 869

122 : 1, 2, 61, 122

643 : 1, 643

781 : 1, 11, 71, 781

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 869,122,643,781, is 1.

Now, the common factors can be found like this.

869:11x 79

122:2x 61

643:643

781:11x 71

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

11 = 11

Therefore, the value for common factors is 11.

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 = 53240437294/(1x11)

LCM = 53240437294/11

LCM = 4840039754

Thus, we can understand that the LCM of 869,122,643,781 is 4840039754.
