Given numbers are 916,218,420,350
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 916,218,420,350 is 52418100.
Find LCM of 916,218,420,350 with Prime Factorization
| 2 | 916, 218, 420, 350 |
| 2 | 458, 109, 210, 175 |
| 5 | 229, 109, 105, 175 |
| 7 | 229, 109, 21, 35 |
| 229, 109, 3, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 229 x 109 x 3 x 5 = 52418100
Therefore, the lowest common multiple of 916,218,420,350 is 52418100.
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 218 x 420 x 350 = 29354136000
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
218 : 1, 2, 109, 218
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
350 : 1, 2, 5, 7, 10, 14, 25, 35, 50, 70, 175, 350
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 916,218,420,350, is 2.
Now, the common factors can be found like this.
916:2x 2x 229
218:2x 109
420:2x 2x 3x 5x 7
350:2x 5x 5x 7
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 5x 7 = 280
Therefore, the value for common factors is 280.
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 = 29354136000/(2x280)
LCM = 29354136000/560
LCM = 52418100
Thus, we can understand that the LCM of 916,218,420,350 is 52418100.
