The LCM of 767,852,635,870,821 is 9879838353060.
Find LCM of 767,852,635,870,821 with Prime Factorization
| 2 | 767, 852, 635, 870, 821 |
| 3 | 767, 426, 635, 435, 821 |
| 5 | 767, 142, 635, 145, 821 |
| 767, 142, 127, 29, 821 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 767 x 142 x 127 x 29 x 821 = 9879838353060
Therefore, the lowest common multiple of 767,852,635,870,821 is 9879838353060.
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.
767 x 852 x 635 x 870 x 821 = 296395150591800
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.
767 : 1, 13, 59, 767
852 : 1, 2, 3, 4, 6, 12, 71, 142, 213, 284, 426, 852
635 : 1, 5, 127, 635
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
821 : 1, 821
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 767,852,635,870,821, is 1.
Now, the common factors can be found like this.
767:13x 59
852:2x 2x 3x 71
635:5x 127
870:2x 3x 5x 29
821:821
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 5 = 30
Therefore, the value for common factors is 30.
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 = 296395150591800/(1x30)
LCM = 296395150591800/30
LCM = 9879838353060
Thus, we can understand that the LCM of 767,852,635,870,821 is 9879838353060.
