Given numbers are 916,870,780,340
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 916,870,780,340 is 88059660.
Find LCM of 916,870,780,340 with Prime Factorization
| 2 | 916, 870, 780, 340 |
| 2 | 458, 435, 390, 170 |
| 3 | 229, 435, 195, 85 |
| 5 | 229, 145, 65, 85 |
| 229, 29, 13, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 229 x 29 x 13 x 17 = 88059660
Therefore, the lowest common multiple of 916,870,780,340 is 88059660.
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.
916 x 870 x 780 x 340 = 211343184000
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.
916 : 1, 2, 4, 229, 458, 916
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 916,870,780,340, is 2.
Now, the common factors can be found like this.
916:2x 2x 229
870:2x 3x 5x 29
780:2x 2x 3x 5x 13
340:2x 2x 5x 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 2x 3x 5x 5 = 1200
Therefore, the value for common factors is 1200.
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 = 211343184000/(2x1200)
LCM = 211343184000/2400
LCM = 88059660
Thus, we can understand that the LCM of 916,870,780,340 is 88059660.
