Given numbers are 785,314,998,403
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 785,314,998,403 is 315722290.
Find LCM of 785,314,998,403 with Prime Factorization
| 2 | 785, 314, 998, 403 |
| 157 | 785, 157, 499, 403 |
| 5, 1, 499, 403 |
Multiply the prime numbers at the bottom and the left side.
2 x 157 x 5 x 1 x 499 x 403 = 315722290
Therefore, the lowest common multiple of 785,314,998,403 is 315722290.
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.
785 x 314 x 998 x 403 = 99136799060
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.
785 : 1, 5, 157, 785
314 : 1, 2, 157, 314
998 : 1, 2, 499, 998
403 : 1, 13, 31, 403
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,314,998,403, is 1.
Now, the common factors can be found like this.
785:5x 157
314:2x 157
998:2x 499
403:13x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 157 = 314
Therefore, the value for common factors is 314.
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 = 99136799060/(1x314)
LCM = 99136799060/314
LCM = 315722290
Thus, we can understand that the LCM of 785,314,998,403 is 315722290.
