Calculate the LCM of 538,952,378,981

Given numbers are 538,952,378,981

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

The LCM of 538,952,378,981 is 753666984.

Find LCM of 538,952,378,981 with Prime Factorization


2 538, 952, 378, 981
3 269, 476, 189, 981
3 269, 476, 63, 327
7 269, 476, 21, 109
269, 68, 3, 109

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

2 x 3 x 3 x 7 x 269 x 68 x 3 x 109 = 753666984

Therefore, the lowest common multiple of 538,952,378,981 is 753666984.

LCM Formula to Find Lowest Common Multiple of 538,952,378,981

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.

538 x 952 x 378 x 981 = 189924079968

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.

538 : 1, 2, 269, 538

952 : 1, 2, 4, 7, 8, 14, 17, 28, 34, 56, 68, 119, 136, 238, 476, 952

378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378

981 : 1, 3, 9, 109, 327, 981

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 538,952,378,981, is 1.

Now, the common factors can be found like this.

538:2x 269

952:2x 2x 2x 7x 17

378:2x 3x 3x 3x 7

981:3x 3x 109

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 3x 7 = 252

Therefore, the value for common factors is 252.

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 = 189924079968/(1x252)

LCM = 189924079968/252

LCM = 753666984

Thus, we can understand that the LCM of 538,952,378,981 is 753666984.
