Given numbers are 677,677,121,691

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

The LCM of 677,677,121,691 is 56604647.

Find LCM of 677,677,121,691 with Prime Factorization

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

677 x 1 x 1 x 121 x 691 = 56604647

Therefore, the lowest common multiple of 677,677,121,691 is 56604647.

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.

677 x 677 x 121 x 691 = 38321346019

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.

677 : 1, 677

677 : 1, 677

121 : 1, 11, 121

691 : 1, 691

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 677,677,121,691, is 1.

Now, the common factors can be found like this.

677:677

677:677

121:11x 11

691:691

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

677 = 677

Therefore, the value for common factors is 677.

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 = 38321346019/(1x677)

LCM = 38321346019/677

LCM = 56604647

Thus, we can understand that the LCM of 677,677,121,691 is 56604647.
