Calculate the LCM of 387,240,173,838

Given numbers are 387,240,173,838

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

The LCM of 387,240,173,838 is 2244197520.

Find LCM of 387,240,173,838 with Prime Factorization


2 387, 240, 173, 838
3 387, 120, 173, 419
129, 40, 173, 419

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

2 x 3 x 129 x 40 x 173 x 419 = 2244197520

Therefore, the lowest common multiple of 387,240,173,838 is 2244197520.

LCM Formula to Find Lowest Common Multiple of 387,240,173,838

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.

387 x 240 x 173 x 838 = 13465185120

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.

387 : 1, 3, 9, 43, 129, 387

240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240

173 : 1, 173

838 : 1, 2, 419, 838

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 387,240,173,838, is 1.

Now, the common factors can be found like this.

387:3x 3x 43

240:2x 2x 2x 2x 3x 5

173:173

838:2x 419

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 13465185120/(1x6)

LCM = 13465185120/6

LCM = 2244197520

Thus, we can understand that the LCM of 387,240,173,838 is 2244197520.
