Given numbers are 485,874,551,870
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 485,874,551,870 is 36878430.
Find LCM of 485,874,551,870 with Prime Factorization
| 2 | 485, 874, 551, 870 |
| 5 | 485, 437, 551, 435 |
| 19 | 97, 437, 551, 87 |
| 29 | 97, 23, 29, 87 |
| 97, 23, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 19 x 29 x 97 x 23 x 1 x 3 = 36878430
Therefore, the lowest common multiple of 485,874,551,870 is 36878430.
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.
485 x 874 x 551 x 870 = 203200149300
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.
485 : 1, 5, 97, 485
874 : 1, 2, 19, 23, 38, 46, 437, 874
551 : 1, 19, 29, 551
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 485,874,551,870, is 1.
Now, the common factors can be found like this.
485:5x 97
874:2x 19x 23
551:19x 29
870:2x 3x 5x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 19x 29 = 5510
Therefore, the value for common factors is 5510.
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 = 203200149300/(1x5510)
LCM = 203200149300/5510
LCM = 36878430
Thus, we can understand that the LCM of 485,874,551,870 is 36878430.
