Given numbers are 420,293,211,679,976
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 420,293,211,679,976 is 614555240880.
Find LCM of 420,293,211,679,976 with Prime Factorization
| 2 | 420, 293, 211, 679, 976 |
| 2 | 210, 293, 211, 679, 488 |
| 7 | 105, 293, 211, 679, 244 |
| 15, 293, 211, 97, 244 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 15 x 293 x 211 x 97 x 244 = 614555240880
Therefore, the lowest common multiple of 420,293,211,679,976 is 614555240880.
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 293 x 211 x 679 x 976 = 17207546744640
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
293 : 1, 293
211 : 1, 211
679 : 1, 7, 97, 679
976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,293,211,679,976, is 1.
Now, the common factors can be found like this.
420:2x 2x 3x 5x 7
293:293
211:211
679:7x 97
976:2x 2x 2x 2x 61
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 7 = 28
Therefore, the value for common factors is 28.
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 = 17207546744640/(1x28)
LCM = 17207546744640/28
LCM = 614555240880
Thus, we can understand that the LCM of 420,293,211,679,976 is 614555240880.
