Calculate the LCM of 148,431,287,406,790

Given numbers are 148,431,287,406,790

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

The LCM of 148,431,287,406,790 is 209708471980.

Find LCM of 148,431,287,406,790 with Prime Factorization


2 148, 431, 287, 406, 790
7 74, 431, 287, 203, 395
74, 431, 41, 29, 395

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

2 x 7 x 74 x 431 x 41 x 29 x 395 = 209708471980

Therefore, the lowest common multiple of 148,431,287,406,790 is 209708471980.

LCM Formula to Find Lowest Common Multiple of 148,431,287,406,790

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.

148 x 431 x 287 x 406 x 790 = 5871837215440

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.

148 : 1, 2, 4, 37, 74, 148

431 : 1, 431

287 : 1, 7, 41, 287

406 : 1, 2, 7, 14, 29, 58, 203, 406

790 : 1, 2, 5, 10, 79, 158, 395, 790

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 148,431,287,406,790, is 1.

Now, the common factors can be found like this.

148:2x 2x 37

431:431

287:7x 41

406:2x 7x 29

790:2x 5x 79

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 7 = 28

Therefore, the value for common factors is 28.

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 = 5871837215440/(1x28)

LCM = 5871837215440/28

LCM = 209708471980

Thus, we can understand that the LCM of 148,431,287,406,790 is 209708471980.
