The LCM of 168,754,767,870,646 is 6034970760.
Find LCM of 168,754,767,870,646 with Prime Factorization
| 2 | 168, 754, 767, 870, 646 |
| 3 | 84, 377, 767, 435, 323 |
| 13 | 28, 377, 767, 145, 323 |
| 29 | 28, 29, 59, 145, 323 |
| 28, 1, 59, 5, 323 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 29 x 28 x 1 x 59 x 5 x 323 = 6034970760
Therefore, the lowest common multiple of 168,754,767,870,646 is 6034970760.
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.
168 x 754 x 767 x 870 x 646 = 54604415436480
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.
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
754 : 1, 2, 13, 26, 29, 58, 377, 754
767 : 1, 13, 59, 767
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 168,754,767,870,646, is 1.
Now, the common factors can be found like this.
168:2x 2x 2x 3x 7
754:2x 13x 29
767:13x 59
870:2x 3x 5x 29
646:2x 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 3x 13x 29 = 9048
Therefore, the value for common factors is 9048.
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 = 54604415436480/(1x9048)
LCM = 54604415436480/9048
LCM = 6034970760
Thus, we can understand that the LCM of 168,754,767,870,646 is 6034970760.
