Given numbers are 407,418,380,343

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

The LCM of 407,418,380,343 is 53048380.

Find LCM of 407,418,380,343 with Prime Factorization

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

2 x 11 x 19 x 37 x 1 x 10 x 343 = 53048380

Therefore, the lowest common multiple of 407,418,380,343 is 53048380.

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.

407 x 418 x 380 x 343 = 22174222840

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.

407 : 1, 11, 37, 407

418 : 1, 2, 11, 19, 22, 38, 209, 418

380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380

343 : 1, 7, 49, 343

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 407,418,380,343, is 1.

Now, the common factors can be found like this.

407:11x 37

418:2x 11x 19

380:2x 2x 5x 19

343:7x 7x 7

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

2x 11x 19 = 418

Therefore, the value for common factors is 418.

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 = 22174222840/(1x418)

LCM = 22174222840/418

LCM = 53048380

Thus, we can understand that the LCM of 407,418,380,343 is 53048380.
