Given numbers are 337,420,471,851
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 337,420,471,851 is 18910734780.
Find LCM of 337,420,471,851 with Prime Factorization
| 3 | 337, 420, 471, 851 |
| 337, 140, 157, 851 |
Multiply the prime numbers at the bottom and the left side.
3 x 337 x 140 x 157 x 851 = 18910734780
Therefore, the lowest common multiple of 337,420,471,851 is 18910734780.
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.
337 x 420 x 471 x 851 = 56732204340
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.
337 : 1, 337
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
471 : 1, 3, 157, 471
851 : 1, 23, 37, 851
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 337,420,471,851, is 1.
Now, the common factors can be found like this.
337:337
420:2x 2x 3x 5x 7
471:3x 157
851:23x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 56732204340/(1x3)
LCM = 56732204340/3
LCM = 18910734780
Thus, we can understand that the LCM of 337,420,471,851 is 18910734780.
