Calculate the LCM of 121,128,998,366

Given numbers are 121,128,998,366

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

The LCM of 121,128,998,366 is 1414317696.

Find LCM of 121,128,998,366 with Prime Factorization


2 121, 128, 998, 366
121, 64, 499, 183

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

2 x 121 x 64 x 499 x 183 = 1414317696

Therefore, the lowest common multiple of 121,128,998,366 is 1414317696.

LCM Formula to Find Lowest Common Multiple of 121,128,998,366

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.

121 x 128 x 998 x 366 = 5657270784

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.

121 : 1, 11, 121

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

998 : 1, 2, 499, 998

366 : 1, 2, 3, 6, 61, 122, 183, 366

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,128,998,366, is 1.

Now, the common factors can be found like this.

121:11x 11

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

998:2x 499

366:2x 3x 61

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 = 5657270784/(1x4)

LCM = 5657270784/4

LCM = 1414317696

Thus, we can understand that the LCM of 121,128,998,366 is 1414317696.
