Given numbers are 136,780,272,658

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

The LCM of 136,780,272,658 is 17450160.

Find LCM of 136,780,272,658 with Prime Factorization

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

2 x 2 x 2 x 17 x 1 x 195 x 2 x 329 = 17450160

Therefore, the lowest common multiple of 136,780,272,658 is 17450160.

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.

136 x 780 x 272 x 658 = 18985774080

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.

136 : 1, 2, 4, 8, 17, 34, 68, 136

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272

658 : 1, 2, 7, 14, 47, 94, 329, 658

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 136,780,272,658, is 2.

Now, the common factors can be found like this.

136:2x 2x 2x 17

780:2x 2x 3x 5x 13

272:2x 2x 2x 2x 17

658:2x 7x 47

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 2x 2x 17 = 544

Therefore, the value for common factors is 544.

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 = 18985774080/(2x544)

LCM = 18985774080/1088

LCM = 17450160

Thus, we can understand that the LCM of 136,780,272,658 is 17450160.
