Given numbers are 984,851,153,974
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 984,851,153,974 is 20798106408.
Find LCM of 984,851,153,974 with Prime Factorization
| 2 | 984, 851, 153, 974 |
| 3 | 492, 851, 153, 487 |
| 164, 851, 51, 487 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 164 x 851 x 51 x 487 = 20798106408
Therefore, the lowest common multiple of 984,851,153,974 is 20798106408.
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.
984 x 851 x 153 x 974 = 124788638448
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.
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
851 : 1, 23, 37, 851
153 : 1, 3, 9, 17, 51, 153
974 : 1, 2, 487, 974
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 984,851,153,974, is 1.
Now, the common factors can be found like this.
984:2x 2x 2x 3x 41
851:23x 37
153:3x 3x 17
974:2x 487
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 124788638448/(1x6)
LCM = 124788638448/6
LCM = 20798106408
Thus, we can understand that the LCM of 984,851,153,974 is 20798106408.
