Given numbers are 909,618,757,456
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 909,618,757,456 is 10773097128.
Find LCM of 909,618,757,456 with Prime Factorization
| 2 | 909, 618, 757, 456 |
| 3 | 909, 309, 757, 228 |
| 303, 103, 757, 76 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 303 x 103 x 757 x 76 = 10773097128
Therefore, the lowest common multiple of 909,618,757,456 is 10773097128.
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.
909 x 618 x 757 x 456 = 193915748304
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.
909 : 1, 3, 9, 101, 303, 909
618 : 1, 2, 3, 6, 103, 206, 309, 618
757 : 1, 757
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 909,618,757,456, is 1.
Now, the common factors can be found like this.
909:3x 3x 101
618:2x 3x 103
757:757
456:2x 2x 2x 3x 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 3x 3 = 18
Therefore, the value for common factors is 18.
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 = 193915748304/(1x18)
LCM = 193915748304/18
LCM = 10773097128
Thus, we can understand that the LCM of 909,618,757,456 is 10773097128.
