Given numbers are 694,420,902,667,410
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 694,420,902,667,410 is 43841069580.
Find LCM of 694,420,902,667,410 with Prime Factorization
| 2 | 694, 420, 902, 667, 410 |
| 5 | 347, 210, 451, 667, 205 |
| 41 | 347, 42, 451, 667, 41 |
| 347, 42, 11, 667, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 41 x 347 x 42 x 11 x 667 x 1 = 43841069580
Therefore, the lowest common multiple of 694,420,902,667,410 is 43841069580.
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.
694 x 420 x 902 x 667 x 410 = 71899354111200
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.
694 : 1, 2, 347, 694
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
902 : 1, 2, 11, 22, 41, 82, 451, 902
667 : 1, 23, 29, 667
410 : 1, 2, 5, 10, 41, 82, 205, 410
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 694,420,902,667,410, is 1.
Now, the common factors can be found like this.
694:2x 347
420:2x 2x 3x 5x 7
902:2x 11x 41
667:23x 29
410:2x 5x 41
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 5x 41 = 1640
Therefore, the value for common factors is 1640.
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 = 71899354111200/(1x1640)
LCM = 71899354111200/1640
LCM = 43841069580
Thus, we can understand that the LCM of 694,420,902,667,410 is 43841069580.
