Given numbers are 639,407,834,703,775
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 639,407,834,703,775 is 1064621829150.
Find LCM of 639,407,834,703,775 with Prime Factorization
| 3 | 639, 407, 834, 703, 775 |
| 37 | 213, 407, 278, 703, 775 |
| 213, 11, 278, 19, 775 |
Multiply the prime numbers at the bottom and the left side.
3 x 37 x 213 x 11 x 278 x 19 x 775 = 1064621829150
Therefore, the lowest common multiple of 639,407,834,703,775 is 1064621829150.
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.
639 x 407 x 834 x 703 x 775 = 118173023035650
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.
639 : 1, 3, 9, 71, 213, 639
407 : 1, 11, 37, 407
834 : 1, 2, 3, 6, 139, 278, 417, 834
703 : 1, 19, 37, 703
775 : 1, 5, 25, 31, 155, 775
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,407,834,703,775, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
407:11x 37
834:2x 3x 139
703:19x 37
775:5x 5x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 37 = 111
Therefore, the value for common factors is 111.
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 = 118173023035650/(1x111)
LCM = 118173023035650/111
LCM = 1064621829150
Thus, we can understand that the LCM of 639,407,834,703,775 is 1064621829150.
