Calculate the LCM of 121,929,210,880

Given numbers are 121,929,210,880

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

The LCM of 121,929,210,880 is 188847120.

Find LCM of 121,929,210,880 with Prime Factorization


2 121, 929, 210, 880
5 121, 929, 105, 440
11 121, 929, 21, 88
11, 929, 21, 8

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

2 x 5 x 11 x 11 x 929 x 21 x 8 = 188847120

Therefore, the lowest common multiple of 121,929,210,880 is 188847120.

LCM Formula to Find Lowest Common Multiple of 121,929,210,880

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.

121 x 929 x 210 x 880 = 20773183200

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.

121 : 1, 11, 121

929 : 1, 929

210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210

880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,929,210,880, is 1.

Now, the common factors can be found like this.

121:11x 11

929:929

210:2x 3x 5x 7

880:2x 2x 2x 2x 5x 11

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 11 = 110

Therefore, the value for common factors is 110.

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 = 20773183200/(1x110)

LCM = 20773183200/110

LCM = 188847120

Thus, we can understand that the LCM of 121,929,210,880 is 188847120.
