The LCM of 951,815,140,861,440 is 19575041640.
Find LCM of 951,815,140,861,440 with Prime Factorization
| 2 | 951, 815, 140, 861, 440 |
| 2 | 951, 815, 70, 861, 220 |
| 3 | 951, 815, 35, 861, 110 |
| 5 | 317, 815, 35, 287, 110 |
| 7 | 317, 163, 7, 287, 22 |
| 317, 163, 1, 41, 22 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 317 x 163 x 1 x 41 x 22 = 19575041640
Therefore, the lowest common multiple of 951,815,140,861,440 is 19575041640.
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.
951 x 815 x 140 x 861 x 440 = 41107587444000
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.
951 : 1, 3, 317, 951
815 : 1, 5, 163, 815
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
861 : 1, 3, 7, 21, 41, 123, 287, 861
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 951,815,140,861,440, is 1.
Now, the common factors can be found like this.
951:3x 317
815:5x 163
140:2x 2x 5x 7
861:3x 7x 41
440:2x 2x 2x 5x 11
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 3x 5x 5x 7 = 2100
Therefore, the value for common factors is 2100.
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 = 41107587444000/(1x2100)
LCM = 41107587444000/2100
LCM = 19575041640
Thus, we can understand that the LCM of 951,815,140,861,440 is 19575041640.
