Given numbers are 293,458,420,336
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 293,458,420,336 is 112722960.
Find LCM of 293,458,420,336 with Prime Factorization
| 2 | 293, 458, 420, 336 |
| 2 | 293, 229, 210, 168 |
| 3 | 293, 229, 105, 84 |
| 7 | 293, 229, 35, 28 |
| 293, 229, 5, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 293 x 229 x 5 x 4 = 112722960
Therefore, the lowest common multiple of 293,458,420,336 is 112722960.
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.
293 x 458 x 420 x 336 = 18937457280
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.
293 : 1, 293
458 : 1, 2, 229, 458
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
336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 293,458,420,336, is 1.
Now, the common factors can be found like this.
293:293
458:2x 229
420:2x 2x 3x 5x 7
336:2x 2x 2x 2x 3x 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 3x 7 = 168
Therefore, the value for common factors is 168.
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 = 18937457280/(1x168)
LCM = 18937457280/168
LCM = 112722960
Thus, we can understand that the LCM of 293,458,420,336 is 112722960.
