Find LCM of 198,490,993,671,609 with Prime Factorization
2 | 198, 490, 993, 671, 609 |
3 | 99, 245, 993, 671, 609 |
7 | 33, 245, 331, 671, 203 |
11 | 33, 35, 331, 671, 29 |
3, 35, 331, 61, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 11 x 3 x 35 x 331 x 61 x 29 = 28404496890
Therefore, the lowest common multiple of 198,490,993,671,609 is 28404496890.
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.
198 x 490 x 993 x 671 x 609 = 39368632689540
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.
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
993 : 1, 3, 331, 993
671 : 1, 11, 61, 671
609 : 1, 3, 7, 21, 29, 87, 203, 609
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,490,993,671,609, is 1.
Now, the common factors can be found like this.
198:2x 3x 3x 11
490:2x 5x 7x 7
993:3x 331
671:11x 61
609:3x 7x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 7x 11 = 1386
Therefore, the value for common factors is 1386.
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 = 39368632689540/(1x1386)
LCM = 39368632689540/1386
LCM = 28404496890
Thus, we can understand that the LCM of 198,490,993,671,609 is 28404496890.
