Given numbers are 394,377,403,421,765

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

The LCM of 394,377,403,421,765 is 1483005620070.

Find LCM of 394,377,403,421,765 with Prime Factorization

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

13 x 394 x 29 x 31 x 421 x 765 = 1483005620070

Therefore, the lowest common multiple of 394,377,403,421,765 is 1483005620070.

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.

394 x 377 x 403 x 421 x 765 = 19279073060910

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.

394 : 1, 2, 197, 394

377 : 1, 13, 29, 377

403 : 1, 13, 31, 403

421 : 1, 421

765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 394,377,403,421,765, is 1.

Now, the common factors can be found like this.

394:2x 197

377:13x 29

403:13x 31

421:421

765:3x 3x 5x 17

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

13 = 13

Therefore, the value for common factors is 13.

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 = 19279073060910/(1x13)

LCM = 19279073060910/13

LCM = 1483005620070

Thus, we can understand that the LCM of 394,377,403,421,765 is 1483005620070.
