Calculate the LCM of 155,124,546,436

Given numbers are 155,124,546,436

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

The LCM of 155,124,546,436 is 18449340.

Find LCM of 155,124,546,436 with Prime Factorization


2 155, 124, 546, 436
2 155, 62, 273, 218
31 155, 31, 273, 109
5, 1, 273, 109

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

2 x 2 x 31 x 5 x 1 x 273 x 109 = 18449340

Therefore, the lowest common multiple of 155,124,546,436 is 18449340.

LCM Formula to Find Lowest Common Multiple of 155,124,546,436

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.

155 x 124 x 546 x 436 = 4575436320

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.

155 : 1, 5, 31, 155

124 : 1, 2, 4, 31, 62, 124

546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546

436 : 1, 2, 4, 109, 218, 436

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 155,124,546,436, is 1.

Now, the common factors can be found like this.

155:5x 31

124:2x 2x 31

546:2x 3x 7x 13

436:2x 2x 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 2x 31 = 248

Therefore, the value for common factors is 248.

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 = 4575436320/(1x248)

LCM = 4575436320/248

LCM = 18449340

Thus, we can understand that the LCM of 155,124,546,436 is 18449340.
