Calculate the LCM of 122,700,308,557

Given numbers are 122,700,308,557

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

The LCM of 122,700,308,557 is 261622900.

Find LCM of 122,700,308,557 with Prime Factorization


2 122, 700, 308, 557
2 61, 350, 154, 557
7 61, 175, 77, 557
61, 25, 11, 557

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

2 x 2 x 7 x 61 x 25 x 11 x 557 = 261622900

Therefore, the lowest common multiple of 122,700,308,557 is 261622900.

LCM Formula to Find Lowest Common Multiple of 122,700,308,557

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.

122 x 700 x 308 x 557 = 14650882400

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.

122 : 1, 2, 61, 122

700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700

308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308

557 : 1, 557

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 122,700,308,557, is 1.

Now, the common factors can be found like this.

122:2x 61

700:2x 2x 5x 5x 7

308:2x 2x 7x 11

557:557

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 7 = 56

Therefore, the value for common factors is 56.

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 = 14650882400/(1x56)

LCM = 14650882400/56

LCM = 261622900

Thus, we can understand that the LCM of 122,700,308,557 is 261622900.
