Given numbers are 764,144,900,931
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 764,144,900,931 is 640155600.
Find LCM of 764,144,900,931 with Prime Factorization
| 2 | 764, 144, 900, 931 |
| 2 | 382, 72, 450, 931 |
| 3 | 191, 36, 225, 931 |
| 3 | 191, 12, 75, 931 |
| 191, 4, 25, 931 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 191 x 4 x 25 x 931 = 640155600
Therefore, the lowest common multiple of 764,144,900,931 is 640155600.
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.
764 x 144 x 900 x 931 = 92182406400
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.
764 : 1, 2, 4, 191, 382, 764
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
931 : 1, 7, 19, 49, 133, 931
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 764,144,900,931, is 1.
Now, the common factors can be found like this.
764:2x 2x 191
144:2x 2x 2x 2x 3x 3
900:2x 2x 3x 3x 5x 5
931:7x 7x 19
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 2x 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 92182406400/(1x144)
LCM = 92182406400/144
LCM = 640155600
Thus, we can understand that the LCM of 764,144,900,931 is 640155600.
