Given numbers are 782,361,399,947
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 782,361,399,947 is 5614139874.
Find LCM of 782,361,399,947 with Prime Factorization
| 19 | 782, 361, 399, 947 |
| 782, 19, 21, 947 |
Multiply the prime numbers at the bottom and the left side.
19 x 782 x 19 x 21 x 947 = 5614139874
Therefore, the lowest common multiple of 782,361,399,947 is 5614139874.
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.
782 x 361 x 399 x 947 = 106668657606
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.
782 : 1, 2, 17, 23, 34, 46, 391, 782
361 : 1, 19, 361
399 : 1, 3, 7, 19, 21, 57, 133, 399
947 : 1, 947
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,361,399,947, is 1.
Now, the common factors can be found like this.
782:2x 17x 23
361:19x 19
399:3x 7x 19
947:947
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19 = 19
Therefore, the value for common factors is 19.
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 = 106668657606/(1x19)
LCM = 106668657606/19
LCM = 5614139874
Thus, we can understand that the LCM of 782,361,399,947 is 5614139874.
