Given numbers are 420,844,889,226,343
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 420,844,889,226,343 is 62317495380.
Find LCM of 420,844,889,226,343 with Prime Factorization
| 2 | 420, 844, 889, 226, 343 |
| 2 | 210, 422, 889, 113, 343 |
| 7 | 105, 211, 889, 113, 343 |
| 15, 211, 127, 113, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 15 x 211 x 127 x 113 x 49 = 62317495380
Therefore, the lowest common multiple of 420,844,889,226,343 is 62317495380.
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 844 x 889 x 226 x 343 = 24428458188960
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
844 : 1, 2, 4, 211, 422, 844
889 : 1, 7, 127, 889
226 : 1, 2, 113, 226
343 : 1, 7, 49, 343
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,844,889,226,343, is 1.
Now, the common factors can be found like this.
420:2x 2x 3x 5x 7
844:2x 2x 211
889:7x 127
226:2x 113
343:7x 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 7x 7 = 392
Therefore, the value for common factors is 392.
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 = 24428458188960/(1x392)
LCM = 24428458188960/392
LCM = 62317495380
Thus, we can understand that the LCM of 420,844,889,226,343 is 62317495380.
