Calculate the LCM of 650,390,878,503

Given numbers are 650,390,878,503

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

The LCM of 650,390,878,503 is 430593150.

Find LCM of 650,390,878,503 with Prime Factorization


2 650, 390, 878, 503
5 325, 195, 439, 503
13 65, 39, 439, 503
5, 3, 439, 503

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

2 x 5 x 13 x 5 x 3 x 439 x 503 = 430593150

Therefore, the lowest common multiple of 650,390,878,503 is 430593150.

LCM Formula to Find Lowest Common Multiple of 650,390,878,503

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.

650 x 390 x 878 x 503 = 111954219000

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.

650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650

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

878 : 1, 2, 439, 878

503 : 1, 503

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 650,390,878,503, is 1.

Now, the common factors can be found like this.

650:2x 5x 5x 13

390:2x 3x 5x 13

878:2x 439

503:503

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 = 111954219000/(1x260)

LCM = 111954219000/260

LCM = 430593150

Thus, we can understand that the LCM of 650,390,878,503 is 430593150.
