Calculate the LCM of 821,950,130,247

Given numbers are 821,950,130,247

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

The LCM of 821,950,130,247 is 10139350.

Find LCM of 821,950,130,247 with Prime Factorization


2 821, 950, 130, 247
5 821, 475, 65, 247
13 821, 95, 13, 247
19 821, 95, 1, 19
821, 5, 1, 1

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

2 x 5 x 13 x 19 x 821 x 5 x 1 x 1 = 10139350

Therefore, the lowest common multiple of 821,950,130,247 is 10139350.

LCM Formula to Find Lowest Common Multiple of 821,950,130,247

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.

821 x 950 x 130 x 247 = 25044194500

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.

821 : 1, 821

950 : 1, 2, 5, 10, 19, 25, 38, 50, 95, 190, 475, 950

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

247 : 1, 13, 19, 247

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,950,130,247, is 1.

Now, the common factors can be found like this.

821:821

950:2x 5x 5x 19

130:2x 5x 13

247:13x 19

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

2x 5x 13x 19 = 2470

Therefore, the value for common factors is 2470.

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 = 25044194500/(1x2470)

LCM = 25044194500/2470

LCM = 10139350

Thus, we can understand that the LCM of 821,950,130,247 is 10139350.
