Find LCM of 680,494,152,984,969 with Prime Factorization
| 2 | 680, 494, 152, 984, 969 |
| 2 | 340, 247, 76, 492, 969 |
| 2 | 170, 247, 38, 246, 969 |
| 3 | 85, 247, 19, 123, 969 |
| 17 | 85, 247, 19, 41, 323 |
| 19 | 5, 247, 19, 41, 19 |
| 5, 13, 1, 41, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 17 x 19 x 5 x 13 x 1 x 41 x 1 = 20659080
Therefore, the lowest common multiple of 680,494,152,984,969 is 20659080.
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.
680 x 494 x 152 x 984 x 969 = 48685353200640
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.
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
494 : 1, 2, 13, 19, 26, 38, 247, 494
152 : 1, 2, 4, 8, 19, 38, 76, 152
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
969 : 1, 3, 17, 19, 51, 57, 323, 969
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 680,494,152,984,969, is 1.
Now, the common factors can be found like this.
680:2x 2x 2x 5x 17
494:2x 13x 19
152:2x 2x 2x 19
984:2x 2x 2x 3x 41
969:3x 17x 19
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 2x 2x 3x 17x 19x 19 = 2356608
Therefore, the value for common factors is 2356608.
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 = 48685353200640/(1x2356608)
LCM = 48685353200640/2356608
LCM = 20659080
Thus, we can understand that the LCM of 680,494,152,984,969 is 20659080.
