Calculate the LCM of 345,506,732,556

Given numbers are 345,506,732,556

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

The LCM of 345,506,732,556 is 128711220.

Find LCM of 345,506,732,556 with Prime Factorization


2 345, 506, 732, 556
2 345, 253, 366, 278
3 345, 253, 183, 139
23 115, 253, 61, 139
5, 11, 61, 139

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

2 x 2 x 3 x 23 x 5 x 11 x 61 x 139 = 128711220

Therefore, the lowest common multiple of 345,506,732,556 is 128711220.

LCM Formula to Find Lowest Common Multiple of 345,506,732,556

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.

345 x 506 x 732 x 556 = 71048593440

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.

345 : 1, 3, 5, 15, 23, 69, 115, 345

506 : 1, 2, 11, 22, 23, 46, 253, 506

732 : 1, 2, 3, 4, 6, 12, 61, 122, 183, 244, 366, 732

556 : 1, 2, 4, 139, 278, 556

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 345,506,732,556, is 1.

Now, the common factors can be found like this.

345:3x 5x 23

506:2x 11x 23

732:2x 2x 3x 61

556:2x 2x 139

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 3x 23 = 552

Therefore, the value for common factors is 552.

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 = 71048593440/(1x552)

LCM = 71048593440/552

LCM = 128711220

Thus, we can understand that the LCM of 345,506,732,556 is 128711220.
