Given numbers are 785,998,314,972,418
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 785,998,314,972,418 is 79576118820.
Find LCM of 785,998,314,972,418 with Prime Factorization
| 2 | 785, 998, 314, 972, 418 |
| 157 | 785, 499, 157, 486, 209 |
| 5, 499, 1, 486, 209 |
Multiply the prime numbers at the bottom and the left side.
2 x 157 x 5 x 499 x 1 x 486 x 209 = 79576118820
Therefore, the lowest common multiple of 785,998,314,972,418 is 79576118820.
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 998 x 314 x 972 x 418 = 99947605237920
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
998 : 1, 2, 499, 998
314 : 1, 2, 157, 314
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
418 : 1, 2, 11, 19, 22, 38, 209, 418
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,998,314,972,418, is 1.
Now, the common factors can be found like this.
785:5x 157
998:2x 499
314:2x 157
972:2x 2x 3x 3x 3x 3x 3
418:2x 11x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 157 = 1256
Therefore, the value for common factors is 1256.
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 = 99947605237920/(1x1256)
LCM = 99947605237920/1256
LCM = 79576118820
Thus, we can understand that the LCM of 785,998,314,972,418 is 79576118820.
