Given numbers are 870,577,942,382,816
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 870,577,942,382,816 is 2047231681680.
Find LCM of 870,577,942,382,816 with Prime Factorization
| 2 | 870, 577, 942, 382, 816 |
| 3 | 435, 577, 471, 191, 408 |
| 145, 577, 157, 191, 136 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 145 x 577 x 157 x 191 x 136 = 2047231681680
Therefore, the lowest common multiple of 870,577,942,382,816 is 2047231681680.
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.
870 x 577 x 942 x 382 x 816 = 147400681080960
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.
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
577 : 1, 577
942 : 1, 2, 3, 6, 157, 314, 471, 942
382 : 1, 2, 191, 382
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 870,577,942,382,816, is 1.
Now, the common factors can be found like this.
870:2x 3x 5x 29
577:577
942:2x 3x 157
382:2x 191
816:2x 2x 2x 2x 3x 17
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 3 = 72
Therefore, the value for common factors is 72.
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 = 147400681080960/(1x72)
LCM = 147400681080960/72
LCM = 2047231681680
Thus, we can understand that the LCM of 870,577,942,382,816 is 2047231681680.
