Given numbers are 781,781,721,779

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

The LCM of 781,781,721,779 is 438655679.

Find LCM of 781,781,721,779 with Prime Factorization

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

11 x 71 x 1 x 1 x 721 x 779 = 438655679

Therefore, the lowest common multiple of 781,781,721,779 is 438655679.

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 781 x 721 x 779 = 342590085299

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

781 : 1, 11, 71, 781

721 : 1, 7, 103, 721

779 : 1, 19, 41, 779

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,781,721,779, is 1.

Now, the common factors can be found like this.

781:11x 71

781:11x 71

721:7x 103

779:19x 41

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

11x 71 = 781

Therefore, the value for common factors is 781.

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 = 342590085299/(1x781)

LCM = 342590085299/781

LCM = 438655679

Thus, we can understand that the LCM of 781,781,721,779 is 438655679.
