Given numbers are 407,361,620,122,821

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

The LCM of 407,361,620,122,821 is 4562115673940.

Find LCM of 407,361,620,122,821 with Prime Factorization

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

2 x 407 x 361 x 310 x 61 x 821 = 4562115673940

Therefore, the lowest common multiple of 407,361,620,122,821 is 4562115673940.

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 361 x 620 x 122 x 821 = 9124231347880

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

361 : 1, 19, 361

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

122 : 1, 2, 61, 122

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 407,361,620,122,821, is 1.

Now, the common factors can be found like this.

407:11x 37

361:19x 19

620:2x 2x 5x 31

122:2x 61

821:821

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

2 = 2

Therefore, the value for common factors is 2.

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 = 9124231347880/(1x2)

LCM = 9124231347880/2

LCM = 4562115673940

Thus, we can understand that the LCM of 407,361,620,122,821 is 4562115673940.
