Calculate the LCM of 409,320,254,451,381

Given numbers are 409,320,254,451,381

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

The LCM of 409,320,254,451,381 is 22489241280.

Find LCM of 409,320,254,451,381 with Prime Factorization


2 409, 320, 254, 451, 381
127 409, 160, 127, 451, 381
409, 160, 1, 451, 3

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

2 x 127 x 409 x 160 x 1 x 451 x 3 = 22489241280

Therefore, the lowest common multiple of 409,320,254,451,381 is 22489241280.

LCM Formula to Find Lowest Common Multiple of 409,320,254,451,381

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.

409 x 320 x 254 x 451 x 381 = 5712267285120

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.

409 : 1, 409

320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320

254 : 1, 2, 127, 254

451 : 1, 11, 41, 451

381 : 1, 3, 127, 381

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,320,254,451,381, is 1.

Now, the common factors can be found like this.

409:409

320:2x 2x 2x 2x 2x 2x 5

254:2x 127

451:11x 41

381:3x 127

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

2x 127 = 254

Therefore, the value for common factors is 254.

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 = 5712267285120/(1x254)

LCM = 5712267285120/254

LCM = 22489241280

Thus, we can understand that the LCM of 409,320,254,451,381 is 22489241280.
