Calculate the LCM of 120,393,988,414

Given numbers are 120,393,988,414

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

The LCM of 120,393,988,414 is 267915960.

Find LCM of 120,393,988,414 with Prime Factorization


2 120, 393, 988, 414
2 60, 393, 494, 207
3 30, 393, 247, 207
10, 131, 247, 69

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

2 x 2 x 3 x 10 x 131 x 247 x 69 = 267915960

Therefore, the lowest common multiple of 120,393,988,414 is 267915960.

LCM Formula to Find Lowest Common Multiple of 120,393,988,414

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 393 x 988 x 414 = 19289949120

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

393 : 1, 3, 131, 393

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

414 : 1, 2, 3, 6, 9, 18, 23, 46, 69, 138, 207, 414

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 120,393,988,414, is 1.

Now, the common factors can be found like this.

120:2x 2x 2x 3x 5

393:3x 131

988:2x 2x 13x 19

414:2x 3x 3x 23

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 3 = 72

Therefore, the value for common factors is 72.

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 = 19289949120/(1x72)

LCM = 19289949120/72

LCM = 267915960

Thus, we can understand that the LCM of 120,393,988,414 is 267915960.
