Given numbers are 174,812,480,821
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 174,812,480,821 is 79998240.
Find LCM of 174,812,480,821 with Prime Factorization
| 2 | 174, 812, 480, 821 |
| 2 | 87, 406, 240, 821 |
| 3 | 87, 203, 120, 821 |
| 29 | 29, 203, 40, 821 |
| 1, 7, 40, 821 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 29 x 1 x 7 x 40 x 821 = 79998240
Therefore, the lowest common multiple of 174,812,480,821 is 79998240.
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.
174 x 812 x 480 x 821 = 55678775040
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.
174 : 1, 2, 3, 6, 29, 58, 87, 174
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
821 : 1, 821
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 174,812,480,821, is 1.
Now, the common factors can be found like this.
174:2x 3x 29
812:2x 2x 7x 29
480:2x 2x 2x 2x 2x 3x 5
821:821
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 3x 29 = 696
Therefore, the value for common factors is 696.
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 = 55678775040/(1x696)
LCM = 55678775040/696
LCM = 79998240
Thus, we can understand that the LCM of 174,812,480,821 is 79998240.
