Calculate the LCM of 120,331,870,452

Given numbers are 120,331,870,452

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

The LCM of 120,331,870,452 is 130162440.

Find LCM of 120,331,870,452 with Prime Factorization


2 120, 331, 870, 452
2 60, 331, 435, 226
3 30, 331, 435, 113
5 10, 331, 145, 113
2, 331, 29, 113

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

2 x 2 x 3 x 5 x 2 x 331 x 29 x 113 = 130162440

Therefore, the lowest common multiple of 120,331,870,452 is 130162440.

LCM Formula to Find Lowest Common Multiple of 120,331,870,452

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.

120 x 331 x 870 x 452 = 15619492800

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.

120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120

331 : 1, 331

870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870

452 : 1, 2, 4, 113, 226, 452

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 120,331,870,452, is 1.

Now, the common factors can be found like this.

120:2x 2x 2x 3x 5

331:331

870:2x 3x 5x 29

452:2x 2x 113

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 3x 5 = 120

Therefore, the value for common factors is 120.

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 = 15619492800/(1x120)

LCM = 15619492800/120

LCM = 130162440

Thus, we can understand that the LCM of 120,331,870,452 is 130162440.
