Calculate the LCM of 128,422,722,773

Given numbers are 128,422,722,773

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

The LCM of 128,422,722,773 is 7536663424.

Find LCM of 128,422,722,773 with Prime Factorization


2 128, 422, 722, 773
64, 211, 361, 773

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

2 x 64 x 211 x 361 x 773 = 7536663424

Therefore, the lowest common multiple of 128,422,722,773 is 7536663424.

LCM Formula to Find Lowest Common Multiple of 128,422,722,773

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.

128 x 422 x 722 x 773 = 30146653696

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.

128 : 1, 2, 4, 8, 16, 32, 64, 128

422 : 1, 2, 211, 422

722 : 1, 2, 19, 38, 361, 722

773 : 1, 773

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,422,722,773, is 1.

Now, the common factors can be found like this.

128:2x 2x 2x 2x 2x 2x 2

422:2x 211

722:2x 19x 19

773:773

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 30146653696/(1x4)

LCM = 30146653696/4

LCM = 7536663424

Thus, we can understand that the LCM of 128,422,722,773 is 7536663424.
