Given numbers are 988,817,425,370
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 988,817,425,370 is 668060900.
Find LCM of 988,817,425,370 with Prime Factorization
| 2 | 988, 817, 425, 370 |
| 5 | 494, 817, 425, 185 |
| 19 | 494, 817, 85, 37 |
| 26, 43, 85, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 19 x 26 x 43 x 85 x 37 = 668060900
Therefore, the lowest common multiple of 988,817,425,370 is 668060900.
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.
988 x 817 x 425 x 370 = 126931571000
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.
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
817 : 1, 19, 43, 817
425 : 1, 5, 17, 25, 85, 425
370 : 1, 2, 5, 10, 37, 74, 185, 370
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 988,817,425,370, is 1.
Now, the common factors can be found like this.
988:2x 2x 13x 19
817:19x 43
425:5x 5x 17
370:2x 5x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 19 = 190
Therefore, the value for common factors is 190.
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 = 126931571000/(1x190)
LCM = 126931571000/190
LCM = 668060900
Thus, we can understand that the LCM of 988,817,425,370 is 668060900.
