Calculate the LCM of 841,928,820,135

Given numbers are 841,928,820,135

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

The LCM of 841,928,820,135 is 148957920.

Find LCM of 841,928,820,135 with Prime Factorization


2 841, 928, 820, 135
2 841, 464, 410, 135
5 841, 232, 205, 135
29 841, 232, 41, 27
29, 8, 41, 27

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

2 x 2 x 5 x 29 x 29 x 8 x 41 x 27 = 148957920

Therefore, the lowest common multiple of 841,928,820,135 is 148957920.

LCM Formula to Find Lowest Common Multiple of 841,928,820,135

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.

841 x 928 x 820 x 135 = 86395593600

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.

841 : 1, 29, 841

928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928

820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820

135 : 1, 3, 5, 9, 15, 27, 45, 135

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 841,928,820,135, is 1.

Now, the common factors can be found like this.

841:29x 29

928:2x 2x 2x 2x 2x 29

820:2x 2x 5x 41

135:3x 3x 3x 5

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 29 = 580

Therefore, the value for common factors is 580.

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 = 86395593600/(1x580)

LCM = 86395593600/580

LCM = 148957920

Thus, we can understand that the LCM of 841,928,820,135 is 148957920.
