Given numbers are 157,778,550,997
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 157,778,550,997 is 33489379550.
Find LCM of 157,778,550,997 with Prime Factorization
| 2 | 157, 778, 550, 997 |
| 157, 389, 275, 997 |
Multiply the prime numbers at the bottom and the left side.
2 x 157 x 389 x 275 x 997 = 33489379550
Therefore, the lowest common multiple of 157,778,550,997 is 33489379550.
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.
157 x 778 x 550 x 997 = 66978759100
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.
157 : 1, 157
778 : 1, 2, 389, 778
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
997 : 1, 997
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 157,778,550,997, is 1.
Now, the common factors can be found like this.
157:157
778:2x 389
550:2x 5x 5x 11
997:997
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 66978759100/(1x2)
LCM = 66978759100/2
LCM = 33489379550
Thus, we can understand that the LCM of 157,778,550,997 is 33489379550.
