Calculate the LCM of 398,121,291,154,936

Given numbers are 398,121,291,154,936

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

The LCM of 398,121,291,154,936 is 15303263976.

Find LCM of 398,121,291,154,936 with Prime Factorization


2 398, 121, 291, 154, 936
3 199, 121, 291, 77, 468
11 199, 121, 97, 77, 156
199, 11, 97, 7, 156

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

2 x 3 x 11 x 199 x 11 x 97 x 7 x 156 = 15303263976

Therefore, the lowest common multiple of 398,121,291,154,936 is 15303263976.

LCM Formula to Find Lowest Common Multiple of 398,121,291,154,936

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.

398 x 121 x 291 x 154 x 936 = 2020030844832

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.

398 : 1, 2, 199, 398

121 : 1, 11, 121

291 : 1, 3, 97, 291

154 : 1, 2, 7, 11, 14, 22, 77, 154

936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,121,291,154,936, is 1.

Now, the common factors can be found like this.

398:2x 199

121:11x 11

291:3x 97

154:2x 7x 11

936:2x 2x 2x 3x 3x 13

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

2x 2x 3x 11 = 132

Therefore, the value for common factors is 132.

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 = 2020030844832/(1x132)

LCM = 2020030844832/132

LCM = 15303263976

Thus, we can understand that the LCM of 398,121,291,154,936 is 15303263976.
