Calculate the LCM of 821,548,266,121

Given numbers are 821,548,266,121

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

The LCM of 821,548,266,121 is 7240369444.

Find LCM of 821,548,266,121 with Prime Factorization


2 821, 548, 266, 121
821, 274, 133, 121

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

2 x 821 x 274 x 133 x 121 = 7240369444

Therefore, the lowest common multiple of 821,548,266,121 is 7240369444.

LCM Formula to Find Lowest Common Multiple of 821,548,266,121

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 548 x 266 x 121 = 14480738888

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

548 : 1, 2, 4, 137, 274, 548

266 : 1, 2, 7, 14, 19, 38, 133, 266

121 : 1, 11, 121

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,548,266,121, is 1.

Now, the common factors can be found like this.

821:821

548:2x 2x 137

266:2x 7x 19

121:11x 11

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

2 = 2

Therefore, the value for common factors is 2.

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 = 14480738888/(1x2)

LCM = 14480738888/2

LCM = 7240369444

Thus, we can understand that the LCM of 821,548,266,121 is 7240369444.
