Calculate the LCM of 727,390,130,686

Given numbers are 727,390,130,686

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

The LCM of 727,390,130,686 is 97250790.

Find LCM of 727,390,130,686 with Prime Factorization


2 727, 390, 130, 686
5 727, 195, 65, 343
13 727, 39, 13, 343
727, 3, 1, 343

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

2 x 5 x 13 x 727 x 3 x 1 x 343 = 97250790

Therefore, the lowest common multiple of 727,390,130,686 is 97250790.

LCM Formula to Find Lowest Common Multiple of 727,390,130,686

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.

727 x 390 x 130 x 686 = 25285205400

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.

727 : 1, 727

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

130 : 1, 2, 5, 10, 13, 26, 65, 130

686 : 1, 2, 7, 14, 49, 98, 343, 686

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 727,390,130,686, is 1.

Now, the common factors can be found like this.

727:727

390:2x 3x 5x 13

130:2x 5x 13

686:2x 7x 7x 7

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 5x 13 = 260

Therefore, the value for common factors is 260.

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 = 25285205400/(1x260)

LCM = 25285205400/260

LCM = 97250790

Thus, we can understand that the LCM of 727,390,130,686 is 97250790.
