Given numbers are 802,871,253,440
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 802,871,253,440 is 3534622520.
Find LCM of 802,871,253,440 with Prime Factorization
| 2 | 802, 871, 253, 440 |
| 11 | 401, 871, 253, 220 |
| 401, 871, 23, 20 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 401 x 871 x 23 x 20 = 3534622520
Therefore, the lowest common multiple of 802,871,253,440 is 3534622520.
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.
802 x 871 x 253 x 440 = 77761695440
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.
802 : 1, 2, 401, 802
871 : 1, 13, 67, 871
253 : 1, 11, 23, 253
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 802,871,253,440, is 1.
Now, the common factors can be found like this.
802:2x 401
871:13x 67
253:11x 23
440:2x 2x 2x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11 = 22
Therefore, the value for common factors is 22.
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 = 77761695440/(1x22)
LCM = 77761695440/22
LCM = 3534622520
Thus, we can understand that the LCM of 802,871,253,440 is 3534622520.
