Given numbers are 1,561,524,655

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

The LCM of 1,561,524,655 is 1469820.

Find LCM of 1,561,524,655 with Prime Factorization

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

131 x 1 x 561 x 4 x 5 = 1469820

Therefore, the lowest common multiple of 1,561,524,655 is 1469820.

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.

1 x 561 x 524 x 655 = 192546420

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.

1 : 1

561 : 1, 3, 11, 17, 33, 51, 187, 561

524 : 1, 2, 4, 131, 262, 524

655 : 1, 5, 131, 655

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1,561,524,655, is 1.

Now, the common factors can be found like this.

1:

561:3x 11x 17

524:2x 2x 131

655:5x 131

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

131 = 131

Therefore, the value for common factors is 131.

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 = 192546420/(1x131)

LCM = 192546420/131

LCM = 1469820

Thus, we can understand that the LCM of 1,561,524,655 is 1469820.
