Find LCM of 608,931,838,812,991 with Prime Factorization
| 2 | 608, 931, 838, 812, 991 |
| 2 | 304, 931, 419, 406, 991 |
| 7 | 152, 931, 419, 203, 991 |
| 19 | 152, 133, 419, 29, 991 |
| 8, 7, 419, 29, 991 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 19 x 8 x 7 x 419 x 29 x 991 = 358744568672
Therefore, the lowest common multiple of 608,931,838,812,991 is 358744568672.
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.
608 x 931 x 838 x 812 x 991 = 381704221067008
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.
608 : 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304, 608
931 : 1, 7, 19, 49, 133, 931
838 : 1, 2, 419, 838
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
991 : 1, 991
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 608,931,838,812,991, is 1.
Now, the common factors can be found like this.
608:2x 2x 2x 2x 2x 19
931:7x 7x 19
838:2x 419
812:2x 2x 7x 29
991:991
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 7x 19 = 1064
Therefore, the value for common factors is 1064.
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 = 381704221067008/(1x1064)
LCM = 381704221067008/1064
LCM = 358744568672
Thus, we can understand that the LCM of 608,931,838,812,991 is 358744568672.
