Calculate the LCM of 936,205,862,438

Given numbers are 936,205,862,438

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

The LCM of 936,205,862,438 is 6037120440.

Find LCM of 936,205,862,438 with Prime Factorization


2 936, 205, 862, 438
3 468, 205, 431, 219
156, 205, 431, 73

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

2 x 3 x 156 x 205 x 431 x 73 = 6037120440

Therefore, the lowest common multiple of 936,205,862,438 is 6037120440.

LCM Formula to Find Lowest Common Multiple of 936,205,862,438

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.

936 x 205 x 862 x 438 = 72445445280

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.

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

205 : 1, 5, 41, 205

862 : 1, 2, 431, 862

438 : 1, 2, 3, 6, 73, 146, 219, 438

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 936,205,862,438, is 1.

Now, the common factors can be found like this.

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

205:5x 41

862:2x 431

438:2x 3x 73

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 3 = 12

Therefore, the value for common factors is 12.

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 = 72445445280/(1x12)

LCM = 72445445280/12

LCM = 6037120440

Thus, we can understand that the LCM of 936,205,862,438 is 6037120440.
