Given numbers are 420,916,319,113
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 420,916,319,113 is 3467000460.
Find LCM of 420,916,319,113 with Prime Factorization
| 2 | 420, 916, 319, 113 |
| 2 | 210, 458, 319, 113 |
| 105, 229, 319, 113 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 105 x 229 x 319 x 113 = 3467000460
Therefore, the lowest common multiple of 420,916,319,113 is 3467000460.
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.
420 x 916 x 319 x 113 = 13868001840
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.
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
916 : 1, 2, 4, 229, 458, 916
319 : 1, 11, 29, 319
113 : 1, 113
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,916,319,113, is 1.
Now, the common factors can be found like this.
420:2x 2x 3x 5x 7
916:2x 2x 229
319:11x 29
113:113
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 13868001840/(1x4)
LCM = 13868001840/4
LCM = 3467000460
Thus, we can understand that the LCM of 420,916,319,113 is 3467000460.
