Given numbers are 716,372,393,778
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 716,372,393,778 is 3393257892.
Find LCM of 716,372,393,778 with Prime Factorization
| 2 | 716, 372, 393, 778 |
| 2 | 358, 186, 393, 389 |
| 3 | 179, 93, 393, 389 |
| 179, 31, 131, 389 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 179 x 31 x 131 x 389 = 3393257892
Therefore, the lowest common multiple of 716,372,393,778 is 3393257892.
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.
716 x 372 x 393 x 778 = 81438189408
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.
716 : 1, 2, 4, 179, 358, 716
372 : 1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, 372
393 : 1, 3, 131, 393
778 : 1, 2, 389, 778
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 716,372,393,778, is 1.
Now, the common factors can be found like this.
716:2x 2x 179
372:2x 2x 3x 31
393:3x 131
778:2x 389
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 3 = 24
Therefore, the value for common factors is 24.
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 = 81438189408/(1x24)
LCM = 81438189408/24
LCM = 3393257892
Thus, we can understand that the LCM of 716,372,393,778 is 3393257892.
