Find LCM of 515,665,198,868,553 with Prime Factorization
| 2 | 515, 665, 198, 868, 553 |
| 5 | 515, 665, 99, 434, 553 |
| 7 | 103, 133, 99, 434, 553 |
| 103, 19, 99, 62, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 103 x 19 x 99 x 62 x 79 = 66426724980
Therefore, the lowest common multiple of 515,665,198,868,553 is 66426724980.
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.
515 x 665 x 198 x 868 x 553 = 32549095240200
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.
515 : 1, 5, 103, 515
665 : 1, 5, 7, 19, 35, 95, 133, 665
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
553 : 1, 7, 79, 553
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,665,198,868,553, is 1.
Now, the common factors can be found like this.
515:5x 103
665:5x 7x 19
198:2x 3x 3x 11
868:2x 2x 7x 31
553:7x 79
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7x 7 = 490
Therefore, the value for common factors is 490.
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 = 32549095240200/(1x490)
LCM = 32549095240200/490
LCM = 66426724980
Thus, we can understand that the LCM of 515,665,198,868,553 is 66426724980.
