Find LCM of 189,744,980,876,830 with Prime Factorization
| 2 | 189, 744, 980, 876, 830 |
| 2 | 189, 372, 490, 438, 415 |
| 3 | 189, 186, 245, 219, 415 |
| 5 | 63, 62, 245, 73, 415 |
| 7 | 63, 62, 49, 73, 83 |
| 9, 62, 7, 73, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 9 x 62 x 7 x 73 x 83 = 9939910680
Therefore, the lowest common multiple of 189,744,980,876,830 is 9939910680.
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.
189 x 744 x 980 x 876 x 830 = 100194299654400
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.
189 : 1, 3, 7, 9, 21, 27, 63, 189
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876
830 : 1, 2, 5, 10, 83, 166, 415, 830
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 189,744,980,876,830, is 1.
Now, the common factors can be found like this.
189:3x 3x 3x 7
744:2x 2x 2x 3x 31
980:2x 2x 5x 7x 7
876:2x 2x 3x 73
830:2x 5x 83
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 2x 2x 3x 3x 5x 7 = 10080
Therefore, the value for common factors is 10080.
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 = 100194299654400/(1x10080)
LCM = 100194299654400/10080
LCM = 9939910680
Thus, we can understand that the LCM of 189,744,980,876,830 is 9939910680.
