The LCM of 883,621,784,980 is 2149504560.
Find LCM of 883,621,784,980 with Prime Factorization
| 2 | 883, 621, 784, 980 |
| 2 | 883, 621, 392, 490 |
| 7 | 883, 621, 196, 245 |
| 7 | 883, 621, 28, 35 |
| 883, 621, 4, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 7 x 883 x 621 x 4 x 5 = 2149504560
Therefore, the lowest common multiple of 883,621,784,980 is 2149504560.
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.
883 x 621 x 784 x 980 = 421302893760
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.
883 : 1, 883
621 : 1, 3, 9, 23, 27, 69, 207, 621
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 883,621,784,980, is 1.
Now, the common factors can be found like this.
883:883
621:3x 3x 3x 23
784:2x 2x 2x 2x 7x 7
980:2x 2x 5x 7x 7
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 7x 7 = 196
Therefore, the value for common factors is 196.
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 = 421302893760/(1x196)
LCM = 421302893760/196
LCM = 2149504560
Thus, we can understand that the LCM of 883,621,784,980 is 2149504560.
