Calculate the LCM of 142,788,438,132

Given numbers are 142,788,438,132

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

The LCM of 142,788,438,132 is 134778732.

Find LCM of 142,788,438,132 with Prime Factorization


2 142, 788, 438, 132
2 71, 394, 219, 66
3 71, 197, 219, 33
71, 197, 73, 11

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

2 x 2 x 3 x 71 x 197 x 73 x 11 = 134778732

Therefore, the lowest common multiple of 142,788,438,132 is 134778732.

LCM Formula to Find Lowest Common Multiple of 142,788,438,132

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.

142 x 788 x 438 x 132 = 6469379136

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.

142 : 1, 2, 71, 142

788 : 1, 2, 4, 197, 394, 788

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

132 : 1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66, 132

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 142,788,438,132, is 2.

Now, the common factors can be found like this.

142:2x 71

788:2x 2x 197

438:2x 3x 73

132:2x 2x 3x 11

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 2x 3 = 24

Therefore, the value for common factors is 24.

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 = 6469379136/(2x24)

LCM = 6469379136/48

LCM = 134778732

Thus, we can understand that the LCM of 142,788,438,132 is 134778732.
