Given numbers are 401,777,249,791,630
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 401,777,249,791,630 is 87668420490.
Find LCM of 401,777,249,791,630 with Prime Factorization
| 3 | 401, 777, 249, 791, 630 |
| 7 | 401, 259, 83, 791, 210 |
| 401, 37, 83, 113, 30 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 401 x 37 x 83 x 113 x 30 = 87668420490
Therefore, the lowest common multiple of 401,777,249,791,630 is 87668420490.
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.
401 x 777 x 249 x 791 x 630 = 38661773436090
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.
401 : 1, 401
777 : 1, 3, 7, 21, 37, 111, 259, 777
249 : 1, 3, 83, 249
791 : 1, 7, 113, 791
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 401,777,249,791,630, is 1.
Now, the common factors can be found like this.
401:401
777:3x 7x 37
249:3x 83
791:7x 113
630:2x 3x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 7x 7 = 441
Therefore, the value for common factors is 441.
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 = 38661773436090/(1x441)
LCM = 38661773436090/441
LCM = 87668420490
Thus, we can understand that the LCM of 401,777,249,791,630 is 87668420490.
