Calculate the LCM of 381,424,346,632

Given numbers are 381,424,346,632

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

The LCM of 381,424,346,632 is 2207821848.

Find LCM of 381,424,346,632 with Prime Factorization


2 381, 424, 346, 632
2 381, 212, 173, 316
2 381, 106, 173, 158
381, 53, 173, 79

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

2 x 2 x 2 x 381 x 53 x 173 x 79 = 2207821848

Therefore, the lowest common multiple of 381,424,346,632 is 2207821848.

LCM Formula to Find Lowest Common Multiple of 381,424,346,632

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.

381 x 424 x 346 x 632 = 35325149568

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.

381 : 1, 3, 127, 381

424 : 1, 2, 4, 8, 53, 106, 212, 424

346 : 1, 2, 173, 346

632 : 1, 2, 4, 8, 79, 158, 316, 632

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,424,346,632, is 1.

Now, the common factors can be found like this.

381:3x 127

424:2x 2x 2x 53

346:2x 173

632:2x 2x 2x 79

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 2 = 16

Therefore, the value for common factors is 16.

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 = 35325149568/(1x16)

LCM = 35325149568/16

LCM = 2207821848

Thus, we can understand that the LCM of 381,424,346,632 is 2207821848.
