Find LCM of 775,821,399,372,406 with Prime Factorization
| 2 | 775, 821, 399, 372, 406 |
| 3 | 775, 821, 399, 186, 203 |
| 7 | 775, 821, 133, 62, 203 |
| 31 | 775, 821, 19, 62, 29 |
| 25, 821, 19, 2, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 31 x 25 x 821 x 19 x 2 x 29 = 29449352100
Therefore, the lowest common multiple of 775,821,399,372,406 is 29449352100.
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.
775 x 821 x 399 x 372 x 406 = 38343056434200
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.
775 : 1, 5, 25, 31, 155, 775
821 : 1, 821
399 : 1, 3, 7, 19, 21, 57, 133, 399
372 : 1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, 372
406 : 1, 2, 7, 14, 29, 58, 203, 406
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 775,821,399,372,406, is 1.
Now, the common factors can be found like this.
775:5x 5x 31
821:821
399:3x 7x 19
372:2x 2x 3x 31
406:2x 7x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7x 31 = 1302
Therefore, the value for common factors is 1302.
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 = 38343056434200/(1x1302)
LCM = 38343056434200/1302
LCM = 29449352100
Thus, we can understand that the LCM of 775,821,399,372,406 is 29449352100.
