Given numbers are 782,144,790,790
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 782,144,790,790 is 22240080.
Find LCM of 782,144,790,790 with Prime Factorization
| 2 | 782, 144, 790, 790 |
| 5 | 391, 72, 395, 395 |
| 79 | 391, 72, 79, 79 |
| 391, 72, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 79 x 391 x 72 x 1 x 1 = 22240080
Therefore, the lowest common multiple of 782,144,790,790 is 22240080.
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 144 x 790 x 790 = 70278652800
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
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
790 : 1, 2, 5, 10, 79, 158, 395, 790
790 : 1, 2, 5, 10, 79, 158, 395, 790
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,144,790,790, is 2.
Now, the common factors can be found like this.
782:2x 17x 23
144:2x 2x 2x 2x 3x 3
790:2x 5x 79
790:2x 5x 79
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 5x 79 = 1580
Therefore, the value for common factors is 1580.
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 = 70278652800/(2x1580)
LCM = 70278652800/3160
LCM = 22240080
Thus, we can understand that the LCM of 782,144,790,790 is 22240080.
