The LCM of 403,280,376,294 is 111373080.
Find LCM of 403,280,376,294 with Prime Factorization
| 2 | 403, 280, 376, 294 |
| 2 | 403, 140, 188, 147 |
| 2 | 403, 70, 94, 147 |
| 7 | 403, 35, 47, 147 |
| 403, 5, 47, 21 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 403 x 5 x 47 x 21 = 111373080
Therefore, the lowest common multiple of 403,280,376,294 is 111373080.
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.
403 x 280 x 376 x 294 = 12473784960
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.
403 : 1, 13, 31, 403
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
376 : 1, 2, 4, 8, 47, 94, 188, 376
294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,280,376,294, is 1.
Now, the common factors can be found like this.
403:13x 31
280:2x 2x 2x 5x 7
376:2x 2x 2x 47
294:2x 3x 7x 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 2x 7 = 112
Therefore, the value for common factors is 112.
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 = 12473784960/(1x112)
LCM = 12473784960/112
LCM = 111373080
Thus, we can understand that the LCM of 403,280,376,294 is 111373080.
